Sold to a person in Belgium. He received it and says he did was unaware that this American model does not funtion in Europe without an AT&T sim card. He is asking me to provide him with the version of the firmware running on it; as well as a prepaid AT&T sim card. My question here is 1) can anyone tell me the version of the firmware that came BEFORE 4.0, because I never upgraded to 4.0 on my 3G and 2) where can I buy the type of prepaid AT&T sim card that he needs? Thanks very much in advance.
