iPhones will now control aircrafts from the ground, thanks to some geeky iPhone app developers. Researchers from the University of California, Berkeley have apparently broken Apple’s terms and conditions when they used the iPhone to guide unmanned aircraft. The Apple Software Developer Kit agreement states that the applications are not to be designed or marketed for automatic or autonomous control of aircraft.

Too late now. And why would they care anyway, they’re having way too much fun. The team uses Mobile Safari to input coordinates and then selects tasks for the unmanned flight that are relayed to the aircraft through a web server. Check out the video below.

If you’re looking to use your DS as a sketchbook or drawing pad, here is a DS paint application that turns your system into one. It’s called colors. All you need are a DS-compatible flash cartridge and a microSD card. It’s a pretty basic program, not even having layers or an undo option yet, but it’s still a pretty impressive app.

More features will be on the way soon, such as DS-to-DS painting that will allow collaboration. You can use a full-size stylus if the DS stylus isn’t doing it for you, and also export projects using Wi-Fi or microSD. Looks like you can create some real masterpieces. Check out a video below.

First there was the pocket guitar app that turned your iPhone into a guitar, now the iAno iPhone app that turns your cellphone into a piano. It won’t be long before iPhone users will be able to meet up in their mother’s basements and play an actual gig. Check out the video after the jump..

iAno will install on Jailbroken iPhones and basically gives you a fully functioning multitouch piano in the form of a four-octave keyboard. The arrow keys at the top are used to navigate. It was developed by one Mr Aardvark, who gave it polyphonic sound that allows five key presses to be heard simultaneously. He plans on updating iAno with a complete 88-key keyboard, and other cool features. So whether you want to be the next Elton John or Barry Manillow, carry your piano with you.
