Unlocked T-mobile iphone 5 on At&t network?

[ticmmae]

Hi
I was wondering if tmobile iphone 5 work on att network or not. Here are my questions:

1. Do i need to get it unlocked to work on att network?
2. If I do get it unlocked, does 3g (HSPA+) work on att network?

I heard that tmobile uses 1700/2100 while att uses 850/1900 for 3g but I also heard that tmobile uses 1900 for edge speed so device should support 1900 mhz. Does anyone know what frequency tmobile iphone 5 support? Will it work flawlessly on att 3g?

Thanks

edit: I also heard that Tmobile iphone 5 is basically same as att iphone 5 but just tweaked little bit. I guess that means it supports att 3g frequencies?

Yes everything will work fine as long as you get tmobile to unlock it.
It will connect to AT&T 3G and LTE fine once unlocked.

Even the LTE? Is there anywhere to look up what kind of frequency tmobile iphone 5 supports?

Good luck on that spent over $200 trying to get a $106 dollar phone to work on their Family Mobile plan no the phone it is the service and they act like idiots FCC has ruled they must unlock and the person that sold the phone refuses to help. You can get the same unlocked phone on Amazon without the hassel
