My HTC Hero was suffering from a tremendous build-up of dust in the bottom left corner of the screen (after being carried in a lint-free HP case for the entire duration of ownership) and the end button peeling off and catching on my thumb. So I decided to send it off to HTC to be fixed under warranty. Well, after a week of them having it in their possession, I called them today to get an update on the RMA. They couldn't pull up any of my information and told me that'd get back to me in 24 to 72 business hours. I'm a bit concerned. Anyone else have this kinda thing happen?Oh what have I done? I'll update as I find out more. Just curious if anything sounds familiar.
