onyx did u ever find a solution to what was wrong??

im having the exact same problem

my phone constantly reboots.. and when it's not.. it hasn't picked up service for the past 2 days.

i tried just the new update and it still wouldn't pikc up signal..

so i wiped my BB using JL commander

and i'm installing an OS.. the newest one my desktop manager could find was 4.2 tho :S
