I downgraded my iphone today from a 2.0.1 to a 2.0. When I take out the original sim card out of the iphone, and put my cingular sim card from my samsung phone, it tells me to activate it. What should I do to make my iphone work with my cingular sim card from my samsung phone? I have at&t.
the steps that I used to downgrade my 2.0.1 to a 2.0 was from this website:
Downgrade iPhone Firmware 2.0.1 to 2.0.0 « iPhone Tutorials - IPHONETUTS
do you think the reason why my iphone doesn't work with my cingular sim card is because when I was downgrading it, the original simcard was in it, and not mine? was I suppose to downgrade the iphone while my cingular simcard from my samsung was in the iphone? please help me. oh yeah, i have a 2nd generation iphone and it's 8GB
basically, all i am asking is what should i do to make my iphone work so when i put my cingular simcard in from my samsung, it will be unlocked and not locked? my iphone is only unlocked only when the original simcard is in it, and not mine. with my sim card inserted, it tells me to activate it.
