is it possible for my i phone to be tracked by the owner who had it tbefore me who had a mac, i bought it off him and installed a monthly sim card in it but he said to me he was able to track its location??
Only way to track it is through a MobileMe subscription. If you restored your phone when you got it all settings would be cleared, such as the MobileMe account information.
Unless the previous owner was a total fool, he/she wiped it before giving it to you. So therefore, no, unless he/she has a MobileMe account on it and enabled "Find My iPhone". Look in the mail settings. Make sure only your email accounts are configured.
