My bb pearl was working fine until monday morning when it decided that it wanted to constantly synch and have the hourglass icon come up about every 3 seonds. it's very irratating and drains the battery in hours, essentially making it impossible for me to take it anywhere cuz it just rus out of juice.
and even though it's contstantly synching, i'm no longer getting new email.
Sounds like Free Memory has gone below the trigger level and the memory manager is working hard to keep the phone working. Try a battery pull (reset) to fix the immediate problem, then look fir the Increase Memory thread in the FAQ message board here.
