I have had my Droid Incredible for 3 days got this error after turning it on today.
android.process.acore is not responding force close. No clue what this means
The error message you received is normally a process/application error. Try to perform a soft reset by removing the battery from your device, wait about 30 seconds, re-insert the battery and power up your device.
Do you have Pandora installed? That was the problem for me. The latest Pandora update started causing that message to pop up a lot on my phone. Even after a soft reset, I would still get the error message a bunch randomly. This is what fixed my issue:
Go into applications and clear the cache for Pandora, and the data, then uninstall and reinstall Pandora.
I would have never figured it out if I didn't find this message on the forum here:

On one of the pages of that post..somebody mentioned the new Pandora update is the issue. Worked for me.
