If you jailbreak your iPhone, you can have access to way better apps through Cydia and Installer. I requested for them to port over the Dynolicious program, but only time will tell if they do or not. With jailbreaking it, I now have MMS, a video camera, the camera can have 4x digital zoom, internet tethering, and all sorts of goodies. I do jailbreaking and unlocking fyi. ;]
