Sometimes people are so dumb!
Both Apple and the hacker community warned owners of patched iPhones that the latest upgrade would brick the device, and advised them to wait a bit with upgrading. These warnings were mostly ignored, and now people complain that their handset became inoperable and started loosing data...
No comment. Anyway, for those affected the iPhone Dev Team is now developing a 1.1.1 to 1.0.2 downgrade.
