I was use to it seemingly locking up during weak signal. Then unlocking when signal is good again. But now it locks, never to return. I cleared out the install, and backup folders on my pc. I also uninstalled-reinstalled palm desktop, but the Treo locks up immediately after hotsync. In both cases I have to remove the battery and put it back in, to soft reset. It does this with no 3rd party apps. I have rtn reset it, no improvement. help.
