I received and installed the update this morning. FAIL!
Upon reboot, the dreaded 'Low on space' warning immediately appeared. Nothing I've tried has cleared the warning.
Icons for some of the app shortcuts on my desktops (IP Cam Viewer, Dolphin Browser HD; USA Today, Vlingo, Pandora, Audible) are missing; the text for the shortcuts is still there, but the app icons are gone. The same (and many other) apps are missing from the "All apps" list, too. AppBrain App Market no longer lists them, either. However, Settings > Applications > Manage Applications lists many of these apps, but with obscure names (e.g., com.rcreations.ipcamviewer) and no logo. I saw some messages earlier in this thread about this damage *perhaps* being related to apps stored on the SD card. When I try to move the problematic apps back to the phone, I get the message: "Failed to move application. The application does not exist."
My wireless credentials are lost; re-entering them isn't working.
I'm wondering whether I should wipe the phone?
