Ok so i'll be on my phone browsing through the net, on my apps etc. then once i get back to my home screen all of a sudden my screen freezes and the "htc screen" pops up (same screen when you reboot your phone) and then i will have to wait a minute or two for everything to load up again. I've had my hero since January and this problem recently just began last week. It happens quite often and it's really irritating. I always clear my cache/data/history. Could it perhaps be some of the applications i downloaded from the market causing this?
