No, I don't have an iPhone (crackberry, baby). However, I do love MGMT and geeky, innovative ideas like this one where The Mentalists play Kids by MGMT on their iPhones and iPod Touches, using only apps downloaded from the Apple App Store. Apps included: Ocarina, Retro Synth, miniSynth, DigiDrummer Lite. Check it.
