If your iPhone apps are crashing a lot, try installing the apps using iTunes instead of your iPhone. This tip was first noticed by Leo Laporte of the Twit podcasting network, and I’ve been finding it to be a great one. There are many other things wrong with the iPhone 2.0 software (sluggishness with typing and contacts), but hopefully Apple will resolve many of these issues in an upcoming software update.

To fix a crashing app, delete it on your iPhone by holding down the app’s icon for a few seconds until the red “X” appears, then tapping it to delete it. Sync the iPhone with iTunes, and the app should reinstall (assuming you’ve backed up that app before). This won’t fix all crashing, but I’ve found it alleviates many crashing issues that involve an app not opening at all or shutting down soon after opening.
