Here is a lis of apps I have:
ASTRO
aTrackDog
Better Cut
Better keyboard
DroidCaddie
Facebook
FBabble
Gensoid
Google Sky Map
GPS Status
Graviturn
Texas Holdem Online
IcViewer
Listen
My Account (T-Mobile)
MyTracks
Nesoid
OpenHome
Pandora
PicSay
Sherpa
SnapPhoto Pro
Spare Parts
SportsTap
Task Panel
WeatherBug
Xtremelabs SpeedTest
As seen in my signature, I have a G1 that is un-rooted. And, as seen above I have TaskPanel which doesn't show much, other than openhome and better keyboard, running in the background when this error occurs. Now, I do have a few widgets on my home screen: Facebook, Pandora, Settings, and WeatherBug. I rarely use Pandora and both the Facebook and WeatherBug get are set to be updated every hour. Could any of these widgets possibly be contributing to the problem?
