IPhone has no service when sim card is in?
I have an iPhone 3gs i bought off of ebay can still get Wi-Fi so i don't know if its a antenna problem or not. It is jail broken. The sim card was all ready activated on another phone so do i need to get a new sim?
To activate it, you will have to restore it back to factory settings. Once it is activated, you will have to re "jail break" it.
R u sure its a iphone from att in the usa?
