Go ahead and restart your phone, however I don't know if that will help much. What you can do is uninstall and reinstall everything that crashes and see how you are then. Also, 2.2 is known to have helped with this problem a bit, so you could upgrade...

Just remember to give your phone a reset after installing new applications.

Try going into settings then general then international and change that to Canada. That worked for me, now I have my apps working.

I switched computers and mine did that. I went and re-authorized my iTunes and redownloaded all of the apps in iTunes and synced my phone and they work again.
