iPhone 3G with Cingular SIM?
Okay, so I just received an iPhone 3G from eBay and it came unactivated (was at "Activate" screen). So I used WinPwn for FW 2.0.1 and everything came out fine, but when I put in my Cingular SIM, I get no bars (not even an "AT&T" carrier sign like my old iPhone). I thought the 3G iPhone was supposed to work with any AT&T/Cingular SIMs? Or does that only happen on a legitimately activated iPhone 3G?
I tried checking/unchecking Activate when building the IPSW, and I started the phone out as a "New iPhone". Any suggestions? Or do I have to wait for an unlock?
