Go into apps
Hit the menu key & select manage apps
Scroll to the text app giving you problems & clear the cache & data.
It should work after that.
The camera app on my wife's phone would not open & this is what fixed it.
Some of the data seems to be getting corrupted in the update process for some apps & people.

I wish I would have known this beforehand. I ended up doing a factory reset.
try restarting the phone a few times, my phone was sluggish as hell this morning after i installed ICS. facebook, home screen, texts - everything kept freezing and it said "would you like to wait or close"? i also didn't have data until i restarted once.
after restarting a few times, try to disable / re-enable the stock text messaging app from the app settings menu
