quick dumb question... whats the difference between the 2g iphone and the iphone 3g? i have a iphone 3g i think fw 2.2 BB 2.28.00. i know the original iphone has the grey back, i have an 8g iphone with a black plastic back which i believe to be an iphone 3g. Its already Jailbroken and unlocked. i really WANT 3.0 for the landscape texting. right now im just waiting on ultrasn0w so i can keep my unlock status but ive seen threads saying that redsn0w can unlock 2g iphones but not 3g phones so im a bit confused.
