TMobile BlackBerry Pearl - problems with Google Applications

Yesterday, a Google applications pack was pushed to the device. After the items arrived, it asked which applications I wanted to install, with the default all items checked. After I pressed ok, the device hung. No keys would work, and after about 10-12 minutes, I had to take out the battery in order to restart the device.

Randomly today, device locked up again, to the point where I was unable to recover without pulling the battery. Normally, I just get a error or error. This time, no keys worked.
