Ok, who is a mobile phone expert? I currently have a have a pretty average Motorola phone on an Optus contract. I have just been offered free a brand spankers iMate JazJam, by a friend who has had it all of 1 hour and already hates it with a passion. Now this phone is on a (bloody expensive) Telstra contract, and I'm with Optus. My question is, are Telstra contract phones locked to the network like pre-paid ones? No offense folks, but I'm not looking for opinions, just somebody who actually knows for sure.
