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?
