[Q] Skyrocket or Samsung Galaxy S 2 Tmobile - T-Mobile Samsung Galaxy S II SGH-T989

i have the option for either but idk which is better i will be using it with tmobile whichever phone i get but arent they almost exactly the same but the only difference is LTE and the headphone jack right?

tmobile doesn't have lte
So with the att model it's better to interchange because you can get lte on att and H+ on tmobile, while tmobile model you only get H+ for both carriers.
Most tmobile users stick to it's model because of warranty and insurance
Headphone jack?
The cosmetics is different... That's it. I think the skyrocket looks more slick.

Good side by side, but some detailed specs missing.. I don't see Skyrocket mentioning having the UMTS1700/2100 (B4) band for access to Tmobile 3G+
EDIT: But here it does show under 4G, http://www.gsmarena.com/samsung_galaxy_s_ii_skyrocket_i727-4303.php
REF: http://www.gsmarena.com/samsung_galaxy_s_ii_t989-4129.php
EDIT2: T989 Also shows as handling HSDPA+ @42 Mbps - I think that is why AT&T opt'd for this new SGS2 with Snapdragon for the same reason, over the previous I9100's Exynos (which is faster than T989 & i727) but can only handle up HSDPA+ @21 Mbs.

The missing details in comparisons is the fault of whoever made those specs. except skyrocket has LTE. basically it.

With the right radio, the Skyrocket supports the 1700(B4) and also supports 42mbps DC-HSPA. It's basically the same phone with the added LTE in case you switch in the future

Nexus vs Galaxy S2 LTE

First off I'm sorry if this is the wrong forum, MODs please move if it is.
Ok so I haven't seen that many reviews on the Rogers version of Samsung galaxy S2 LTE (not the HD from korea). Right now I debating between which one I should pick up. I had a Samsung S1 (i9000m from Bell) and I've always loved it. I love modding phones (ie custom ROM and other stuff). I plan on doing on these as well. The pros for S2 LTE is that: it is LTE compatible, 8mp back 2mp front camera, slight better processor (though I doubt there will be a big difference in performance).
Wheres the Nexus pros is that it is HD and has ICS, slightly better battery life, and of course being nexus, first in line for updates. The screen is also slightly bigger. It just sucks that the LTE from rogers isn't HD like the korean counterpart.
I do live in a LTE enabled zone so I will be able to utilize it (6GB data plan). Any thought on what phone is better? I've went in and tested both out and I honestly can't decide. I love the screen on the nexus but also the camera + LTE on the S2 balances out.

Personally I'd go with the Nexus because the processor is almost up to par with the Exynos in the GSII vs the GSII LTE has a Qualcomm Snapdragon, which for day to day tasks is good, but GPU performance is nowhere near the Mali 400 in the Exynos.
AT&T has the Galaxy S II Skyrocket HD which is pretty much the Korean GSII with a 4-button layout. It sounds exactly like what you're looking for.
Had the at&t galaxy s2 lte and took it back. Qualcomm snapdragon sucks compared to the omap in fhe nexus, but had to use it for lte.
Nexus is so much more fluid day to day i would not look twice at the lte unless you really need limited lte .
Sounds like nexus is still the top. I might just pick it up. Idk something about the shape of the phone just doesn't catch me. Btw is the nexus 4G capable? While looking through the specs, it said its 3G or maybe that website is wrong?

It is an HSPA+ device. Which is the faster 3G on AT&T (like "4G"). It is not LTE on AT&T.

In USA, AT&T and T-Mobile markets HSPA+ as 4G.
LTE is marketed as 4G.
Therefore, the GSM & LTE both supports 4G.
I don't believe it supports Tmo's 42mbps network, however. Or does it?

Yes very true, but considering OP is comparing to a 4G LTE device on AT&T, it is a good idea to make the distinction that the Galaxy Nexus is HSPA+ and the Skyrocket (SGSII LTE) is an LTE phone.

It is only 21mbps. Anything over 14.4mbps T-Mobile calls 4G, however.
T-Mobile only has a couple 42mbps phones I think. The SGSII and the HTC Amaze 4G are the only 2 that come to mind.

Should i buy a t-mobile branded Galaxy S II or the AT&T branded Skyrocket

The title says it all im really not sure which one. I have T-Mobile but i can get the AT&T skyrocket now for a little bit cheaper than the T-mobile Galaxy S II. My problem is that i am not down to lose my HSPA+ speeds with T-mobile. Because the phone will be AT&T and not T-mobile. But I do know that the skyrocket does indeed have the T-mobile HSPA+ speeds. I am fairily android savvy so i can most likely figure out all that stuff you know? But if I do go the AT&T route does the phone work flawlessly just like it would as if I had the T-mobile version? Or will battery life take a hit? etc?

Skyrocket does not support t-mobile's HSPA+ if it did there would be no need for the different variants. If you use 4g get the t989. You can buy it from me if you want i will give you a better deal than your getting i bet
Actually IT does, but how much are you selling yours for?

You need to do a bit more research. It does not have the exynos chip set it has the same chip set the t-mobile variant has.
Id get the Skyrocket. Just 'cuz if you ever switch to ATT, you'll get LTE.

OH that's right.. I was thinking of the i777.. and not i727. Stupid numbering. I guess there's no reason to get it other than LTE bands? It should have that last I heard.. don't think that's a deal breaker.

[solved.. won't work] T-Mobile 3G/4G on AT&T SGH-I747

I've got an unlocked AT&T Galaxy SIII, and I only get Edge for my data connection. Do I need to flash a T-Mobile radio? APN settings look okay, as far as I can see.
Also, can I flash a T-Mobile ROM and use Wifi calling, or is that asking too much?
I searched and couldn't find anyone asking these questions in the Q&A forum....
there are already like 3 threads below this one concerning the 3g/4g topic on a att sg3 working on tmobile. No it will not work because att sg3 does not support the aws tmobile frequencies. you will only be able to get edge. NOW if it were a tmobile sg3 on att then it would work.
All the threads I could find in this form on my search went the other way: T-Mo phone on AT&T.
Does anyone actually know whether a T-Mobile modem on an AT&T phone would work or not? I looked at the main board in my phone, and it's labelled with both SGH-I747 and SGH-T999, which makes me think the internals are fully identical.
I'd like to know this too! I also have an AT&T Galaxy SIII and was seriously considering moving to T-Mobile because of the new unlimited data plan they were going to start offering on 9/5. I had also looked through this forum, and could only find questions of the situation the other way around, T-Mob GSIII phone on AT&T network.
Basically, was wondering:
- is there a hardware limitation that APN settings and/or installing a new modem will not get me good data speeds?
- would I need to burn a new modem?
- I'm assuming at minimum I'd need new APN settings, and am assuming T-Mobile would be able to help with that. Right?
Thanks, really interested in being able to do this!

Where did you see that the boards were labelled the same?
AFAIK, the radio's are different and flashing a T-mobile modem could possibly brick your device. It would be much easier to buy a T999 and use it on T-Mobile (it'll even work on AT&T 3G if you want to switch back, no LTE though).
The SoCs are different. Flashing a T-Mobile modem will not give you T-Mobile HSPA.
Looks like I didn't take any pictures of that side of the phone while I had it open, and I'm not eager to pop it open again. It definitely listed both models on the PCB. If I'm remembering correctly, it's on the same side as the SIM and SD card slots, so it's just matter of removing the back plate to see it, no more disassembly than that.

Do you have part numbers for the two? According to wikipedia, they are the same Snapdragon S4 MSM8960. I just find it hard to believe that they would be different, though if they have the same pinout, that would explain the markings on my PCB.
This has been rehashed countless times. They are not the same phone. If the phones were the same, people would not be in here asking if they were the same. The MSM8960 comes in more than one flavor, with different modem parts. Yes, the CPU's are the same, but the MODEMS ARE DIFFERENT. It is an S4 Qualcomm part that comes in many different configurations. Instead of just reading until you get to some information that reinforces your preconceived notion, try reading a little further into the links at the bottom of the page and elsewhere. Seriously, if you really really don't think that Qualcomm would make different versions of the same chip, or configure them differently for the hundreds of different customer requirements, then fine, don't believe me, but it defies logic. Sorry about being an ass.

Thanks for the useful response. For those looking for even more detail, here's a link: http://www.qualcomm.com/sites/default/files/common/snapdragon-specs-06.07.12.pdf
According to that the MSM8960 (chip in I747?) has a "World Mode" modem, while the MSM8260a has a UMTS modem.
Edit: Ah, and I see both of you have answered this question before, which I would have found if I searched on MSM8260a. The threads have been dead for over a week, so I'm not surprised I missed them, but thanks for answering the same questions again.

T-Mobile uses a frequency for their 3g and 4g network that only T-Mobile branded phones have. Any other GSM phone will never get 3g or 4g on T-Mobile network unless it supports the T-Mobile band, which I believe is 1700MHz. It's limited by hardware. Nothing you can do to the phone will give you the 3g/4g you have to have a T-Mobile branded device.

Not completely true. Since The Galaxy SII and the Galaxy Note (AT&T) have software radios, you can flash a radio from the TMO GSII and get 4G on TMO. I was running mine and many customers of mine like that for months until i switched phones.

It works fine for me, the area i'm in does not support 4G on the 1900MHz frequency so I can definitely confirm my stock non-rooted AT&T i747 galaxy SIII is working on T-Mobile USA's 4G data network.

This is NOT TRUE, please be careful when making such "absolute" statements -- I just got a ATT i747 from craigslist, and it DOES work with the $30 Walmart plan - on 4G and LTE (depending on location).
The TRUE ANSWER IS -- IT DEPENDS -- if you live in an area that was recently upgraded to LTE (in my area was 02/13), you can get LTE/4G since t-mobile added support for it on 700 MHz (band 4) AWS (unverified - source: youtube video named "Tmobile 4G on att i747 gs3 data fix". Sorry I am not allowed to post web-links yet).
Anyway, I DO get 4G/LTE, I guess I was lucky

[Q] T-889, N7100, or N7105

I'd really to get on T-Mobile's prepaid plans or Solavei and I'm not sure which device would be the smartest to purchase. I live in Portland, OR if that helps. It seems like they all offer upsides but I'd be willing to spend a bit more for the device that will be the most future proof (if that's possible).
I'm on a Tmo value plan, and where I'm at, there is almost no Magenta coverage. I got the T889 for the WiFi calling and maybe, just maybe, for the LTE. When and if Tmo ever brings real 4G to our area, I'll already be running the right device.

The T-Mobile version seems to be the one to go with considering the pentaband 3G radio hardware. The inclusion of the LTE radio is also a big plus. None of the other Note2 models work on everyone's 3G like the Note2 does.

Keep in mind if you purchase the n7100 international it won't actually work on T-Mobile's HSPA+ network and instead you will be treated to its 200ish kbps speeds, and on a super phone like the Note 2 that's just sad. :crying: Take it from someone who's used the International Edition Note1 on their prepaid for a few months now...it SUCKED! I'm now on their Value plan with the GN2 and the phone and the download speeds are exceptional!

Yeh, the T-Mobile version has all the right hardware for the USA. Not only does it include the 1700 MHz band needed for current hi-speed T-Mo 3G in most places, and LTE capability that should work on T-Mo and ATT when ready, but it's 42Mbps capable, too. The N7100 has none of that. The N7105 has 42Mbps but still no 1700 MHz, and the LTE probably won't work in the US.
BTW, T-Mo is upgrading towers to provide hi-speed 3G via 1900 MHz band, which the N7100/05 support, but it's not widely available yet.
Now let's just hope CyanogeMod comes to the T-Mo Note II, since the N7100 is officially supported. That would make it THE best cellphone in the world IMO.

Agreed! That's what I'm chomping at the bit for right now-some CM LOVE! This is by far the most function packed stock software, but it's over-bloated IMO. I want speed and infinite customizations!
This conversation brings up a good point though. Has anyone found a good source for the differences of the models and what will or won't work on all three of them i.e. n7100, n7105, and the T889? It was easy with the first Note because it was your either qualcomm or exynos, but now all Note 2's are Exynos. I can imagine many bricks happening if there are major unknown hardware differences.

Yeah, that would be great. Im looking for a site where I can see if the n7100 is the same in the outside (housing) as t889.
Since I know that the front crystal is the same for all three models, att, international and tmo. Also that the plastic back door (battery door) is the same on the att and the tmo models. Not yet sure if the n7100 also because I havent opened one of does yet (n7100), the other two are the same in plastic housing too. Thats great at time of replacing parts.

The i317 t889 n7100 have same housings.
ALSO
In the link I provided before you can see that there are only two real differences between them:
Cellular Networks:
TMobile t889 GSM 850/900/1800/1900, UMTS 850/900/1700/1900/2100
N7100 GSM 850/900/1800/1900, UMTS 850/900/1900/2100
Maximum Speed Download: t889 (42 Mbps) N7100 (21 Mbps)
Get a t889. Im using tmobile pre paid plan on my note 2 and my wife is running solavei on hers. Everything runs fine and speeds are fine. I try to compared using both my tmobile and solavei on a unlock n7105 and n7100 and speeds arent that great. Feels like im running on edge for some reason.

You need umts band 1700 to run tmobile 4g. So yes you where on edge on the n7000 since the only model with band 1700 is the t889

Nights SPIDER is correct, but I'm going to clarify a bit in case anyone else stumbles across this in the future.
The other two models will only get T-Mobile 3G speeds when in a refarmed area that T-Mobile has 1900MHz bands. Most of the country is still rocking the 1700MHz band, so those two models won't work at all on it and only get EDGE speeds.

What does this mean...?

when I go through the specs for the AT&T and Tmobile variants for the note 2, I come across a difference in the following
AT&T,
GSM Quad-band: 850/900/1800/1900 MHz
Tmobile
Frequencies and Data Type GSM Quad-band: 850/900/1800/1900 MHz UMTS: Band I ,band II, Band IV (Dual-band1700/2100 MHz), Band V
What does the dual band mean? Is it for Tmobiles 4G network?
I thought all the Note 2's in the US had the same LTE radio
please shed some light,
thanks
1700 MHz/2100 MHz UMTS (WCDMA) AWS is currently T-Mobile's 4G network.
T-Mobile will have LTE up and running sometime within next year (2013).
Yes T-Mobile Galaxy Note 2 devices do have LTE. But it is now not activated. T-Mobile will activate the LTE within T-Mobile's Galaxy Note 2 when they get their LTE service up and running within your area.
How to activate the LTE and running on another carrier is a good question. This I get bits and pieces. But not a full step-by-step process yet.
The T-Mobile Note II is pentaband; it will work on AT&T and T-Mobile 3G/4G (not LTE though as of now). I think that's what you're getting at.

I believe that we can get the LTE up and running with other carriers. I know that I got LTE working on my GN2 (SGH-T889). We just need to learn how to get the LTE running with other carriers. That is really the question. When we figure that out then this might be able to be applied to other GN2 devices.
Tmobile hasnt turned on lte yet. From what i understand once they do our note 2's should be able to utilize it.

Tmobile uses 42.2 mbps dual channel hsdpa.
Afaik, At&t uses 21.1 mbps hsdpa.
Lte(long term evolution) is a different technology not yet active for Tmobile customers.
Real World, my friend with a Galaxy nexus on Tmobile network gets about 8mbps while I get 14mbps. Galaxy nexus has the 21.1mbps capable modem.

You're talking about something called DC-HSPA (Dual Channel/Carrier), which is basically what you said: Using 2 frequencies of HSPA(+) to achieve basically double the throughput.
Is it a hardware limitation (as in slightly modified Qualcomm LTE Chipset) in the AT&T Note 2 that 42mbps is not supported compared to T-Mobiles version? Or it is software / firmware-controlled?

It could be software (on the modem level, which is low-level stuff and separate from the ROM); T-Mobile's Galaxy S II was basically AT&T's Skyrocket with LTE disabled. You could actually flash a T-Mobile S2's modem onto a Skyrocket to get it to work on T-Mobile frequencies (but you can't get LTE enabled on the T-Mobile S II as far as I know).
would you say the note 2 from verizon is any better since it also includes a CDMA radio? Also, though LTE only works in the upper 700 frequency, any change a modem update or firmware change will allow the verizon version to work on T-mobile or AT&T network?

No; CDMA is useless unless you're going to be using it on the carrier it came from. I'd say the T-Mobile version is the best (in terms of working with the most networks), then the AT&T version (because it has LTE), then the International version (because it's the AT&T version without LTE), and after that the Verizon one because Sprint are jerks because they use "embedded SIMs".
