so i got a replacement from the store with 2.1 firmware...

[vr6pwr]

Ok .. so here's the deal... I made the big mistake of upgrading to 2.2 (hence I'm a tmobile customer, using a sim adapter card) .. without knowing the consequences... long story short, I went to the apple store today and pretty much told them a bunch of BS and the guy took a second to give me a new phone.

Lucky me the phone they gave me still hasn't been ungraded to the 2.2 firmware.... so I'm of course gonna jailbreak and unlock with the Pwnage tool like I did with my previous phone.

My question is, if I restore the backup file from my old phone would it force me or actually upgrade to the 2.2 by itself ?

Thanks a bunch !

I don't believe that it would actually update the OS, to restore from backup, but thats just a guess.

You can still go to 2.2 with a custom firmware without the baseband update. In this way you'll have 2.2 and also have your 2.1 baseband. I've tested my phone on Tmobile on 2.2 with 2.1 baseband.
