so i got the eris on tueday and i love it, but last night it started locking up. i ws making calls for a cab and about every line was busy so i would quickly end call wait a second and then try again. about the 6th one i couldnt hang up. none of the touch screen buttons wee working and i couldnt even hang up on the regular button so i had to pop the battery. then later that night i was fielding some text messages for the new year and it froze on me again on the lock screen. the touch screen wouldnt work and couldnt even hit the hangup button to make it go black again so popped the battery once again. then it just happened about 5 minutes ago. i got the task killer when it booted up and only a few apps i wanted shut off. but something was interesting, thursday morning there was a error "htc sensor" and it restarted on its own. should i be worried about it?
