Unfortunately, this phone is being discontinued which really sucks because it is Sprints best phone, hands down. I called all the Radio Shack stores and Best Buys, none of them have the phone. Only way to get the phone is to call sprint directly, or be lucky enough to live near a sprint store that still carries it. It really is unfortunate. When I went to buy my M1, the salesperson kept trying to get me to buy the Muziq phone. Your best bet is to call sprint.
Also, go to bestbuy.com and look for cellphones. You can actually buy the phone online.
