Hello, My wife has a white iphone 4s but she is going to China shortly to use for a few months time, and the phone is currently locked to Telus in Canada. She likes the phone but her usage is very basic. The problem is there is no freaking way to completely unlock the phone unless we can go Telus for at least 3 months of postpaid plan and then pay $50 to them to unlock. We don't have enough time, so this is not possible. I understand there is ways to unlock using things like r-sim 3, but that, even if without bugs, would prevent us to upgrade to iOS 6 when the time comes. We find a deal on refurbished Nexus S for around $150. I am thinking of selling our iphone 4s and go with Nexus S instead (I know Nexus S is getting Jellybean already). Is this a good idea and is the $150 for Nexus S a really good deal? Not sure if my wife likes the idea though.
