Some units require a foreign SIM, some do not. The iPAQ has a known issue with unlocking that can be difficult to get corrected.
As far as "encouraging" people to use unlocked handsets, that is not T-Mobile's intention. Using a non-T-Mobile handset can cause issues for you, the customer, such as not being able to get it replaced through Customer Care if something goes wrong with it and not having the phone flashed correctly for T-Mobile. Every handset T-Mobile offers has been through testing with T-Mobile's engineers to ensure it works well with their network, and since last year, they only use handsets with AMR technology to help the handset interface even better with the network. It is all part of their campaign to delight the customer. One more note on unlocking, until you have been active 90 days on the system, they will not give you the unlock code for your handset, and you may only request one unlock code every 90 days. This is whether you bought the handset from them or not. So if you buy a locked handset somewhere that is not locked to T-Mobile and expect that T-Mobile will help you unlock it, your number must be active for 90 days before they will give you the code. Code requests can be done via their website or by a call to Customer Care. [Non-text portions of this message have been removed] ------------------------ Yahoo!
