Been using this app for messaging online buddies for a month or so. Useful as it doesnt need any personal detail exchange and quick to set up. Great for sending free pics too. BUT it stopped working yesterday and I uninstalled it to try reinstalling.. Where has ffm gone on the app store?! I can't find it to reinstall it! Anyone else having this problem? Mostly though does anyone know what's going on and if I can get the app back? Thanks.
