Free iPhone app - SoundHound with FREE unlimited IDs (was $4.99) SoundHound is an app that can recognize a song for you by listening to your singing, humming, or sound source. There is a free version of it that allows 5 free IDs (the number of times it will recognize a song for you). You pay $4.99 for unlimited IDs. However, if you write a review for SoundHound in the iTunes store, this will give you free unlimited IDs. I was under the impression that it only gives you a couple free ones but for some reason, after writing a review, my app was upgrade to the UNLIMITED IDs plan for free. I checked my purchase history to make sure this was not a mistake and so far there are no charges for the Unlimited Option ($4.99). Get the free app here: http://itunes.apple.com/us/app/so...54941?mt=8 Then install it on your iPhone, iTouch, iPad, etc. Immediately click the "Upgrade" button at the bottom (it will show that you have 5 IDs remaining) Choose the first option to earn more id's" than review the app in the itunes store (scroll down until you see the rating stars and click on that, then choose to review it) MAKE SURE TO GIVE IT 5 STARS! Review it however you want. When you are finished, the icon that shows how many IDs remaining will go from 5 to infinity!
