Recently, I have acquired an iPhone 3GS, and like all my other ipods, I jailbroke it (and unlocked it). The thing is, is that it says this iPhones carrier is Vodafone UK 12.0 even though I removed the SIM card, and I currently live in Canada. Here's where the questions begin: 1. I currently have a slide phone with no SIM card; if I go to my carrier and request a SIM card with my plan on it, will they give/sell it to me or will I need to buy a new plan for this phone? 2. Do they care if it's an unlocked phone? 3. Since this phone is from the UK apparently, will it be compatible with a SIM card from Canada? And will it get service etc? Thanks.
