OK I am planning on getting an iPhone 3GS soon but I dont plan on getting a plan. So the phone is going to cost me a pretty penny. Due to the recent change I plan on going to an Att store and buying one out right. Is it all possible for me to easily jailbreak and unlock a new phone so I could put a prepaid SIM card in it and use it like any normal person would with the plus of having it jailbroken. Also one more quick question. I keep reading in some places about the phone being "tethered". what does this mean?
