Hi there folks, I am trying to use a jailbroken unlocked Iphone 3GS Software 3.1.2 with bell. I never registered the SIM with the Iphone but now they know I have one. How could they have found out? Is there a way for me to keep them from knowing that I have an Iphone? The reason for this is that I want to use my old data plan without getting to pay extra fees. Any insights, solutions, would be greatly appreciated. Dali.
