[Q] Sprint Rom on ATT

I just switched from Sprint to ATT because Sprint still doesn't have 4G LTE in my area. Currently using JB's Jellybomb on my Sprint Note 2. Can I use the same rom on ATT or will it brick my phone?
I've searched to forums, and see conflicting answers, so forgive me if this has been addressed before.
You won't brick it but I could not configure it for data

I'm in for answer as well...
I mean, it's safe to flash any ROM for the Note 2, whether it's Sprint, t-mo, or international because we have the same hardware(aside from fm radio)?
Then maybe stab at apn settings for network to work=win?
Yea if its packed with a radio etc your borked. I tried jelly bomb on here but I couldn't get the APN settings configured correctly. It may have to do with a CDMA base which didn't allow me to set APN but that's only speculation.

I wasn't a big fan of Jellybomb.
Anyway That would be a no go bro brick possibility is very high.

Will att unlock my phone?

My brother bought his phone outright from att and I want to use it on tmobile, will they unlock it since it's paid for or will they make it a hassle?

u should ask this in the AT&T Galaxy s4 forum... you'll get a quicker and accurate response
1 should be posted in Q and A, and 2 you may have more luck posting in the ATT section. There may be someone here to help, but thr majority of us are on tmobile and have been for a while. But there is a couple of people who have jumped ship recently.

AT&T has a far less restrictive policy when it comes to unlocking phones verses T-Mobile, even after the "international travelers" change. When I unlocked a phone from AT&T it was all taken care of via online chat - and the phone was not paid off, still early in contract.
Read this thread over in the AT&T GS# Forum, the steps will apply to any AT&T phone. http://forum.xda-developers.com/showthread.php?t=1962453&highlight=unlock+galaxy+s3

Actually a 1 minute call to AT&T would probably get you the answer quickest.

Actually if you flash the new T-Mobile premium suite 4.1.2 directly on att i747
Everything works new style 4g icon
Same everything and Wifi calling works
The phones are so close in relation that its all compatible
Hspa+is displayed as 4g
Read about it the package was just released recently

To flash you need to root it correct? and when i put in a t mobile sim card from a co worker i got 4gs speed ? so maybe the tmobile is just saying that to try and sell a phone

[Q] 4.3 T-Mobile update anyone have news

ok so i want to know why it is that Sprint and AT&T have pushed 4.3 to the Note II but Verizon and T-Mobile act like what update that just seams a little odd if you ask me does anyone know the reason why we are still stuck in the out of the box 4.1 and dont have 4.2 or the 4.3 update is T-Mobile and Verizon both just not care anymore about the owners of the Note 2 and more worried about the Note 3 owners or just trying to push everyone on the Note 3 to make more money
T-Mobile is wifi calling, most likely.

This^ and modem (aka radio) in relation. Probably that is the delay. Your guess is as good as mine...
you know t-mobile has the note 3 with wifi calling so it cant be that hard to fix the radio i could maybe see i just think like verizon they are trying to drum up note 3 sells

Use on verizon

My s3 is unlocked and I have tried putting my verizon sim card in and setting the apn. I will get full signal with voice and data for about 30 seconds before switching to no signal. While I have signal I can make calls and a text or use data. Is verizon kicking the phone off their network or is there something else I need to change?

Might be because you're using (I assume) a gsm device on a CDMA network. I have no idea really. Might want to ask in the Verizon forums where they are familiar with that network.

Yeah I know that the att s3 is GSM vs verizon being CDMA however with their lte am card I wasn't sure. I'm not even sure which verizon forum to ask in. I have a feeling I'll get flamed if I ask in the verizon s3 forum.

You shouldn't. Just say you asked here first but was told to as there as well since they're more familiar with what will or won't work on their networks. Ask if anyone's heard of any success using the I747 there.
Whenever you have device or rom type problems, its best to ask in the devices forum. But if you are having network connectivity issues it can be wise to ask someone with knowledge of the network you're trying to use.
If they do give you a hard time, let me know and I should be able to find someone who's willing to help.
If you explain why you are asking there it shouldn't be a problem though.
