I would suggest a hard reset. Sounds like a recent install might have corrupted/conflicted with something else.

You could try uninstalling programs one by one, but by that point I think a hard reset is your best option. Once its reset and you have all your contacts re-entered, I would then suggest backing up your phone with a back-up program ( I use Resco back up).

After that, take some care to monitor your phone how it acts after each new install. you might find the culprit that way and if it starts to crash again, you can use your saved back up to get your phone back to a state you can work with it.
