Text messaging issues

[Chubbydog]

Anybody else having problems receiving text messasages? I won't get any for a few hours, then all of a sudden, I'll get 10 or 15 of them come through. I look at what time they were sent, and it was several hours before I received them. It's causing problems with people thinking I'm ignoring them. Is there any fix, or could it just be a bad software update?

I've only had this problem since the last update to 4.0.4. Before that, I never had a problem.
