So, I cannot figure out what's going on, but my phone is so screwed up. Whenever I try to do download anything from the market, it just says "download started..." but never actually downloads anything (even after leaving it overnight). When I click on the "people" widget, the phone has a processing wheel, but I eventually get the message: "Activity HTC Sense (in application HTC sense) is not responding." I force close it and it goes to a black screen, never reloading Sense. I have to turn off the phone to make the phone usable. I left my phone to sync overnight and it did nothing except leave the sync wheel in the notifications panel. What do I do?!! I don't want to have to reinstall everything!
