I now have an Iphone 4, but think my Iphone 3G was stolen, i have the serial number and just want to know if it is active, no other information then i will call the police.
No one will give me that information, not att or apple...........even though i don't use it anymore it is still mine......
When you activated your new phone, did you use the same phone number & account info? If so, then your account is associated with your new phone so who ever took it wouldn't be able to make calls or text with your number.
I would definitely make sure that you change any passwords you may have had stored on your old phone (as well as the password associated with your Apple ID.
