apps won't load

[MKnight]

Just bought a 16GB iPhone 3 days ago. Immediately upgrade to 2.1 firmware when I got home because it was running 2.01. Installed the Facebook app + Fring, Apple remote, and Tap Tap.

Today I tried launching any of these apps and they try to load then disappear, nothing happens...


I rebooted the phone and no difference, none of the apps I installed want to load anymore.

Anyone run into a situation like this?

By reboot did you just hold down the sleep/wake button and slide to turn off? (Restart)

If so try to Reset, by holding down the sleep/wake button and home button, until the Apple logo appears.

If that doesn't help try Restoring your iPhone.
