VoIP has been ushered onto the iPhone in quite a few incarnations, but we'd wager than none of 'em are as useful as iCall. Said application is currently in beta form, though a release isn't quite ready for the public at large. Put simply, it enables iPhones to switch from GSM to WiFi (when WiFi is nearby, of course) on-the-fly in order to save cell minutes and bypass the hassle of manually changing over. Interested?
