hi, everyone i have just bought my first iphone 4, from ebay i think it may be barred, dont worry i am not going to ask how to unbar it i was just wondering if it could be something i am doing wrong. i bought the phone on ebay and went to collect and pay cash for the phone it was brand new still with the cellophane. it is on t-mobile i have put my t-mobile simcard in and i cannot make any calls in or out i cant even even make an emergency call. i did however have my number switched to the new micro sim and they said it could take 24hours to start working again, but surely i should be able to make an emergency call.
