2.2.1 update

[xpsm1730]

So I have the iphone 3g currently 02.28.00 firmware and Version 2.2(5g77) running on yellowsnow/tmobile

I was trying to download a game and got a msg saying I need the 2.2.1 update

Can I update to that and still run on t-mobile? If so, how do I update?

Thanks as I'm clueless on this hacking stuff..

The problem is that if you update through iTunes it will make you download the 3.0 update which is jailbroken but yet has been unlocked (coming out soon) Your best bet is to wait until ultrasn0w comes out (check here frequently http://blog.iphone-dev.org/ or these forums). Then you can update to 3.0, jailbreak with redsn0w and unlock with ultrasn0w.

Its out now, right?

Is there a step-by-step guide on the entire installation process?

There certainly is.

Just update to 3.0 with iTunes, and then:

- first, jailbreak with Redsn0w like this:

- second, unlock with UltraSn0w like this: http://www.iclarified.com/entry/index.php?enid=4253

Read the tutorials carefully before setting out
