HTC Droid Eris :: System Error Message And Force Close Option

Anyone else having issues with the phone and a system error message with something about com.htc.provider and it only gives you the option of a "force close" button. Sometimes that is all that happens and once you hit the force close the message goes away, at least for a while. Other times when this happens it deletes all of your text strings. I have 2 lines and 2 droids, both were having the same issue, did the factory resets, went to the store with both and finally gave in and took 2 refurbished phones to try and fix issue, both refurbished phones started doing the same thing immediately. I am in process of arguing with verizon about not wanting another eris to replace these.
