What's the difference between the the three speeds 4g, HSDPA, and HsDPA+?
4G is the 'average guys' description of 4G. All it means is 4th Generation and it's the all encompassing term for HSPA and HSPA+.
HSPA = 14.4 Mbps (download)
HSPA+ = 21.1 Mbps (download)
There's also the 42 Mbps network T Mobile rolled out in Vegas and a couple other places, no phone is capable of it, not even sure if they have network cards for it yet. I think it's referred to as HSPA++
On both modes the phone is still limited by the hardware to 14.4Mbps down and about 5Mbps up.
HSDPA is up to 14.4Mbps (384kbps up) 3GPP release 5
HSPA+ is the next release of HSDPA / HSUPA combined?? (3GPP release 7, max 84Mbps up 22Mmbps down)
HSPA+ is marketed as 4G in the US.

I'd go with the Verizon model
CDMA network:
Dual-band 800/1900 MHz
CDMA2000 1xRTT/1xEVDO/1xEVDO rev. A and IS-95A/B voice or data with up to 1.8 Mbps

(Band frequency, HSPA availability, and data speed are operator dependent.)
It's also the easiest to get SIM unlocked should you decide to use is for GSM in the US.

Thanks for the fast feedback, but how will I unlock the sim because i've been reading the forum and it seems to make the phone work on all networks - it is still in progress?
So I busted my AT&T tilt2, fell off my car and kinda exploded and so I bought one on Ebay...
I got it working data and voice on AT&T, but it only shows Edge not 3G.
Can I flash the stock AT&T ROM on this thing and get my 3G and basically make it like my stock AT&T phone?? This one was a U.S. Cellular phone.
Or do I need to do something more in depth?
Hmm seems the US cellular phone bands are not compatible with AT&T 3G from reading a bunch of searches. Is it compatible with T-mobile?
Phone is a bit diff than my tilt2.. Has a normal headphone jack beside the mini usb port, no PTT button and a few other differences.
On another note the Edge internet seems as fast as I usually get from 3G, I guess maybe less folks using edge.. Since edge is all I get at my other property anyway I guess I'll stick with it for now. Don't want to change anything as I'm grandfathered on the unlimited PDA personal plan, will see what happens with the new windows 7 phones and newer android phones..
If you want 3g speeds you need to have a tilt 2.. fairly certain

Hi,
Does the HOX support HSPA+ it only shows th H and not H+
I cant get HSPA+ on my HOX,
I'm on Tmobile UK and when i use the sim in my GS2Ii get hspa+ with superfast internet.
Why is this the case?

Speed is slow and theres no sign either
HSPA+ is a bit confusing, because as a standard I think the differences get confused. The Atrix is not truly conformant to HSPA+ but was sold as an HSPA+ phone. HSPA+ has been used as a marketing aid to say " we can now go even faster". Some phones do not display an H+ but still achieve those speeds
The HTC One X (quad-core verison) is rated to
HSDPA 21Mbps and HSUPA 5.76 Mbps
Since no network in the UK goes faster than that at present, that should be fine!
HSPA technically maxes out at 14.4Mbps. HSPA+ can max out at 56Mbps. So the HTC One X is somewhere in the middle!
Yes, it supports HSPA+ upto 21MBPS. Not the dual carrier 42MBPS one that T- Mo uses.

You're thinking of the USA T-Mobile. The UK one only supports up to 21Mbps but Three and T-Mobile UK will be rolling out their DC-HSPA+ network in september which supports up to 42Mbps speed.
The One X does support HSPA + 21.1Mbps, however, there is no H+ icon in sense, only the H icon. So you will never see a H+ icon even if you are on HSPA+. You should be seeing fast speeds when compared to other phones. Do a speed test on your One X and compare it to the S2. There should only be a tiny difference. Unless you're capped at 3.6Mbps by T-Mobile which most people are.
Also, check your APN settings.

Right, the dual carrier 42 is USA T Mo only. The global variant only supports upto 21, which isn't dual carrier. Which doesnt matter because we only have 21MBPS support anyways. And yes, it just doesnt show the H+ icon.

hi
how can I get HSPA on my htc one x
I live in America and was thinking about ordering the S4 GT-i9500 for Wolfson Audio chip reason. I wanted to use Tmobile because they have the best prices. I saw that the i9500 network is:
Network: 2.5G (GSM/ GPRS/ EDGE): 850 / 900 / 1800 / 1900 MHz; 3G (HSPA+ 42Mbps): 850 / 900 / 1900 / 2100 MHz
And from https://en.wikipedia.org/wiki/T-Mobile_US#HSPA.2FHSPA.2B_.224G.22_upgrade, I see that HSPA+ uses 1700/2100 Mhz. It also saids:
Band IV AWS consists of the 1700 / 2100 MHz band pair. Data is transmitted upstream on 1700 MHz and downstream on 2100 MHz. A device must support both frequencies to access T-Mobile's AWS data services.
I don't understand, but sellers on ebay are claiming i9500 will work with Tmobile's 4G in America. How would the i9500 work on the American Tmobile network if it doesn't use the 1700 frequency? What would be the draw back?
Tmobile is refarming its 1900Mhz band for hspa+. If you're in an area that has it you could get 4G with that and pretty good speeds. You won't get LTE and if you're in an area without the 1900 you'll get 2g speeds.
Here's a more technical explanation.
T-Mobile used to exclusively use the AWS (1700/2100) spectrum for DC-HSPA+42mbps. They are currently refarming this for LTE use.
HSPA+21mbps is being moved to the 1900mhz spectrum. So, in areas that have been refarmed, you will have HSPA+ access (NOTE, no 42mbps). In areas that are not refarmed, you'll be limited to EDGE service.
I have a Galaxy S2 GT-i9100, so I have the same limitation. I signed up with T-Mobile about 2 months ago and on a weekly basis, I'm seeing towers refarmed. They intend to have it nearly completed by end of 2013, thus limiting the areas you'll be on Edge only. Eventually, their entire 1900mhz network will be HSPA+ 21, with their AWS network being LTE.

Their HSPA+ network on 1900mhz is limited to 21mbps.
Basically, their network prior to refarming was:
1900mhz (PCS) - EDGE
1700/2100mhz (AWS) - DC-HSPA+ 42mbps
They have since acquired a TON of PCS and AWS spectrum from; failed AT&T merger, Verizon spectrum swap, and MetroPCS merger.
This will allow them to expand to new markets currently not served, as well as expand bandwidth in existing markets. So, their current plans are to refarm the network to;
1900mhz (PCS) - HSPA+ 21mbps
1700/2100mhz (AWS) - LTE
There will be some limited spectrum for the old EDGE (PCS) and DC-HSPA+ 42 (AWS) available for legacy devices, but that will eventually (at least 2020, most likely) go away. The goal is to have LTE over their core network by mid-2014, and HSPA+ 21mbps being the expanded fallback network. T-Mobile will also be taking part in the 600mhz auction in mid-2014. Their network plans will be made more clear (VoLTE, LTE-A) after that auction. Lower frequencies allow for better building penetration. T-Mobile is currently silently lobbying the FCC (through other groups) to remove Verizon and AT&T from that spectrum auction for the sake of competition.

so eventually you'll be able to access the 21mb range? Thus, if in a refarmed area, you could get 21mb with a i9500?
For explanatory purposes: Ever noticed how, if connected to a 100mbps LAN, you don't ever see 100mbps? That's link speed, not real world.
Applied here, HSPA+ has a top link speed of 21mbps (assuming both ends are compatible). DC-HSDPA has a top link speed of 42mbps. Real world performance will be 3-8mbps on the former, and 5-15mbps on the latter. I've seen spikes up around 12mbps and 25mbps, but those are incredibly rare. Bottom line is, do not expect LTE speeds. I currently have a phone that has 21mbps HSPA support on PCS (1900mhz), and on T-Mobile, I get 6-7mbps in most HSPA areas.
I hope that helps.

Wow, kind of considering the I9500 again. I live in Austin, Texas. How will I know if Tmobile converted here and if I can get the 6-7mpbs in HSPA where ever I am here? Also, right now I have a Nexus S with 3G. I have to admit that I only am able to get 3G(Tmobile) about 50% of the time and the rest is edge speed. Would HSPA consistency be this bad?

If you got the Nexus S model sold for T-Mobile, that has AWS support. That means that switching to a PCS 3G phone like the i9500 means that AT BEST you will have the same Edge/3G coverage ratio you have now, and at worse you'll have mostly Edge coverage. Your 3G data speeds will be faster in the areas you get it though. It will be a tradeoff.
EDIT: Here's a user-generated map of areas that have had 3G and HSPA+ refarmed to PCS. Looks like a few rowers directly in Austin have been refarmed. This is a massive project by T-Mobile and is nowhere near being complete. However, an areas HAS to be refarmed in order for them to launch LTE, so refarmed markets (that already offered 3G/4G AWS service) are the ones that are getting LTE eventually.

i m wondering that does out beloved phone(SGH-t989) supports 4G.
i know i should search web before posting here but trust me i surfed alot for the clarification.
i'm posting question because when i was using stock rom the logo says(displays) 4G symbol and now this day when i put my 4G sim in slot i do not get network. on top it, my friend said, in cyanogenmod 4g is not supported so i want to know that is really our phone supports 4G or that cyanogenmod don't let me go into 4G world ?

nope. HSPA+ is technically a form of "4G", but not the most current LTE (which, i assume, youre referring to)
