I've had problems with an 8830 in my office as well. It's been a while since I've carried an 88xx but when I was having problems with my Bold hanging I was doing a lot of backup, wipe, restore cycles. With the Bold and DT 4.6 I could backup and restore messages and PINs. Might be worth a look before you move him over. And consider doing the restore before activation as the BES may lockout restoring the messages database.
