iPhone on T-Mobile Network Upgrade?

[brandoncarr]

After doing some searching, I've come up empty handed... I have a couple of questions.

I have an unlocked iPhone, and I'm on the T-Mobile network. It's currently running on firmware version 1.x.x. Now that Winpwn has been released, can I just use the firmware from the Apple website, and pwn it with this wonderful program? Or, are there extra steps that I need to go through. I don't want to brick the phone again, and just want to make sure that restoring it through iTunes with a pwned version of 2.0 is going to be okay. Thanks!

I wouldn't suggest going to 2.0 unless there's something on there that you really want. It's made my phone constantly lose service when I should have full bars.

I've actually had great success with it up to this point. 1st Gen iPhone/2.0/T-Mobile are a good mix. No probs. Feel free to PM me if anyone is having any issues with it.

Same here, 1st gen iPhone on 2.0 jail-broke and unlocked and pwned. Not a single issue on TMO.
