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 !
