Hi, First post - was browsing and thought i should let everyone know what happened to my desire after about a month. Bascially, it corrupted my SD card, lost everything on it and the SD card itself was not recoverable. I'm seeing similar reports on these forums but no clear answers other than to try another SD card. Not the best idea. The problem in my case was NOT the 4gb SD card that came with the phone but after a HTC repair turned out to be a faulty SD card reader in the phone. I wouldn't have known it was this (i got no info back in the post) if i hadn't rang up & the guy told me. There's no way i'm the only one...so back up your SD cards often just in case!!! I'm loving the phone, it's just one of those things.
