i've had a blackberry since 2003, and been updating my OS myself never having a problem till now but my last issues are leaving me at a loss and i cant figure how to solve them.
any help is appreciated!

in the last month, I upgraded my 8100 to OS 4.5.0.69 and have DT 4.6 on my laptop and havent been able to run a backup since. last night, figured it was corrupted msgs on my handheld that was preventing the backup so that's working now.

but i also cannot update my OS and media sync cant connect to my handheld when trying to sync itunes. mediasync does list my PIN when connected but can never go through with the sync. it did work when i first installed it though.

im trying to upgrade my OS from .69 to .81 or .93 but after installing the new OS on my laptop and deleting the vendor file, i run DT and nothing happens. ive tried to go to the app loader on the DT to try to start the process but that doesnt work either.

i updated a friend's curve's OS 3 weeks ago and that work but i doubt that should be causing any complications for me as ive uninstalled the OS for the curve update off my laptop and ive even uninstalled and reinstalled DT 4.6 on my laptop but still cant update my OS or get mediasync to work.

any ideas?? help! haha
