Considering it must have cost you several hundred dollars just to get out of your contract I'd think $50 wouldn't cause too much grief. And if you travel buying non contract unlocked phones is a good (but initially expensive) option.
PS how much did you have to pay in early termination fees to Telus?
You are misunderstanding. I have no option to pay $50 to unlock my phone. I would have done that. I have no option to unlock my phone at all. It will stay locked to Telus for as long as it exists, as they are greedy pieces of garbage that do not unlock iPhones under any circumstances whatsoever.
