Does anyone else have issues on Motorola Atrix?

[kamikaze168]

Hi,

TestTube on my Atrix will play via 3G for like 30 seconds and then
freeze. If I exit and restart it works again for 30 seconds again.
Works fine over wifi internally or externally, also works fine on my
wife's HTC Aria on 3G, both are AT&T, hers is android 2.1 mine is
2.2.1

Any help or suggestions would be appreciated.

Thanks,
Peter
