Using the Treo 600 and AT&T.

Let's say I go out of range of my wireless network and someone sends me a text message. When I go back ino an area with coverage, I receive an alert that reads, "You have SMS messages waiting for you. Do you want them delivered to your phone?"

I'll select "Yes," but then... nothing, they never appear on my phone. I've tried sending myself messages afterwards to try to "push" the network, but, alas, no dice.

Anyone come across this? Is there a fix?
