My first iphone never crashed, but my newer iPhone has crashed a couple times in the 3 years I've had it... hard resets have always fixed it but it's a bit annoying. Of course the android (Motorola) phone I had between the two used to crash all the time (apps crashing, phone rebooting when travelling, losing it's setup every firmware update, the list was long and I only had the POS for 6 months)... so I guess I still feel grateful to have an iPhone. Sadly I've got to go back to Android after this since Apple saw fit to cripple the newest iphones with bad design decisions.
