On mine it did mess up the email (as I said I had to use the program I linked to above to fix it) but the data connection is still working.. Im on a touch pro 2.. I see most people with issues are not on a TP2.. maybe that is the issue? I know the software isnt made specifically for the TP2 but maybe there is something in the phone that it came from that is similar to the TP2....
If anyone can figure out what is causing all of the issues that would be great! especially if someone fixes the cab
