Hi guys, So I recently bought an iPhone 4 from a friend and I am planning on jailbreaking and unlocking it due to my cell provider being T-mobile. The question I have is, if I do so, is there any way to track it? My friend was a little sketchy about how he got the iPhone and I am a little worried he either found it or stole it :/. I still would like to use it however. Thanks in advance!
