Ok - I had email nicely syncing to an Exchange account via the BIS, and Bluetooth based sync to everything else via my PC - all just as I wanted
Fiddling about, I managed to get the destop redirector in DM 5 fired off, then all went wrong. New 'Desktop' service books insist on getting sent to my BB, sync is screwed up (wanting to sync via the redirector only) etc etc. Even DM now (via the redirector) thinks my BB is connected to it OTA (and I don't mean via Bluetooth)!
HOW CAN I BACK OUT OF THIS? I want to kill off the redirector and Enterprise activation from starting for good and go back to where I was. I don't mind purging my BB if I have to but if I JUST do that the whole enterprse thing will come back like a bad penny I think, service books and all.
