Motorola RIZR Z3

Hi, I have an unlocked RIZR and am using it on my tmobile account. Anyways, I tried downloading my first game on this phone and it's giving me an application error. I called T-Mobile and they said since it's an unlocked phone, it won't download to my phone. So, I was just wondering if there was any way of getting newer games to this phone..


Thanks in advance.
