Google voice not checking for messages Just recently I've missed a few text messages via Google Voice because the alert hasn't come through.  As soon as I open the app the backed up messages arrive and trigger the alert.

I have background notifications turned on (or at least I think I have - Background data is "enabled")

Any ideas?
I'm having the same problem here.

Check running services under Settings --> Applications --> Running services.  Is the Google Voice update service stuck on restarting?

If so, you might want to try and remove apps that are running services.  In other words, uninstall apps that you aren't using that are causing excessive amounts of services to run and eat up your free memory.
