jailbroken, 2.28, yellowsn0w but still not working
I'm on 2.2.1 with bb 2.28. My iphone's jailbroken and I've installed yellowsn0w. My phone was locked on FIDO (canada). Now I'm in the US and I tried using my friend's SIM CARD (T-Mobile). I turned off my iphone, put the T-mobile SIM card, turned it on and it's only in emergency mode and asks to be connected to itunes. When I connect it to itunes, itunes says "The sim card inserted in this iphone does not appear to be supported."
Anyone knows what's going on? Thanks.
