Same thing has happened to me twice so far. I had to pull battery both times. Its pretty annoying considering how long it take for BB to start back up.
I am on .75 and I downloaded Slacker and have had it playing none stop for the last 4 hours. I have had several phone calls during this time, paused, played and no lockups or anything funny going on. I have also hooked it up to my pc and and cached my two stations I have it set up for. Also have it working with Bluetooth.
Flycast on the other hand would drop the stations with some kind of error after about an hour or so of listening.
I was just listening to Slacker for the first time and I thought that it was just me and the time I was listening to it (2am). I thought maybe they were doing online maintenance. I hope it keeps getting better, it seems to be a great concept.
Dang Storm just started playing music again 10 minutes later and locked up as you all said. I could not get it to go off and had to finally do a battery pull myself.
In another thread, I was told to hold the 'red button' (hang up) for about 15 seconds and the phone will shut down, then you can fire it up again. BUT the Slacker app won't come back until you do a batpull.
