Phone locked up

[enroy]

Okay, I mentioned about possibly having a memory leak issue since I d/led .net. Now my PPC is locked up.

Here's what I have done:

I recently added the map4pda program and the .net function for it to work, that's it. However, a few hours after using the map and turning it off and making sure it was actually off in the running programs area, I noticed the PPC kept giving me error messages that my memory was running low. Now, I installed both programs on my 2G mini sd card. I thought well I will just let the bugger resta a bit. I go to use it this morning and the screen is stuck in transition from portrait to landscape mode. the stylus is completely unresponsive. Whenever I push the end call button (the red phone button) I get a delayed beep after about ten seconds. The background is gone and is still stuck in that transition between modes.

What the heck shall I do???

Also, it won't sync now. The computer can't see it.
