T Mobile User thinking about getting an iPhone 4.

Aloha

Tried using the search feature on my phone and nothing really came up.

I currently have the 3g model and its slowly breaking down on me. I'm deciding either on the HTC 7 or iPhone 4.

How is the performance like on the iPhone running on T-Mobile? Does it lag a lot or does it run pretty much the same as 3g just with new features and what not?

Thanks for reading. Input is greatly appreciated.

The iP4 itself is a great device.
On tmobile it works great aswell, except just like on your 3g, it will only have edge internet.
The phone itself will be MUCH faster, but the network internet speed will be just about the same.

Phone for phone the Ip4 is much better, but if internet speed is your concern you'll want to get a native t-mobile phone, such as the HD7

Thank you. Im on the hunt for the iPhone 4 now. Is there any advice on purchasing such as Firmware? Programs that will unlock/jailbreak without problems?

Try to get one with firmware 4.0.1 or 4.0.2. Those 2 are safe to unlock. Or if they preserved the baseband. For the baseband the highest that can be unlocked right now is 01.59.xx
