There had been a lot of talk about Tmobile's new SIM unlock policy, now that they have gotten rid of service contracts and phone subsidies, and now that they are selling the iPhone. They have a new policy that their own message board CS reps are linking to: here it is. If you read it like an intelligent adult it would appear to suggest that their unlock policy depends on whether you are postpaid or prepaid customer, and whether you bought your phone at full retail price. There is a separate Bold section heading for people who pay full price, and under that heading the only requirements are to be in good standing and to fax the a copy of the receipt. Unfortunately, that is NOT how Tmobile themselves are interpreting their own policy. They insist that you must wait either 40 days (postpaid) or 60 days (prepaid) before they will unlock the phone. In discussions with them (hours long discussions) it becomes clear that the third section heading on Full price phones is irrelevant. They admitted to me on the phone that they should delete it from the unlock document because it is misleading. It is, at best, misleading; at worst it is an outright lie. Their policy document says they will unlock full price phones, but they will not. Honestly, if they had told me this before I signed up, I wouldn't have been that bothered. But I read the document and talked to the Rep in a Tmobile corporate store before buying, and it was clear that their policy was to unlock phones bought up front at full price. But now that I'm signed up with them, they refuse to give the unlock code. I will now wait the needed 40 days, but I thought others might benefit from the clarification.
