Existing T-Mobile 2 Go/New Phone

I have T-Mobile To Go Service, if I decided to buy a new "unlocked" phone will my present T-Mobile SIM card work on an unlocked phone or do I have to buy a locked phone from T-Mobile?

Thanks

Unlocked phones work fine as long as they support at least GSM 1900 and preferably both GSM 850 and 1900.

I'm using an unlocked Rogers Nokia 6590i for my TMo to go and it works fine in my Moto P280 and Moto RAZR V3 too.
