I doubt it. I had this same phone with at&t. I paid $400 for it when it first came out (been out like a week) and the rep on the phone SWORE to me that when cingular took over I'd have no prob using my new $400 phone. Then they switched everything to cingular, and I got a nice little letter that said that when my contract was up, I had to buy a CINGULAR branded phone, at full price, because my moto v600 wouldn't work, and they wouldn't unlock it so that it would. mMode was at&t's web service. It worked for cingular's service on my phone. You may be able to change the keys if you look in your book.
