ok so i was on my ipod touch on safari and saw this developer posted 25 promo codes for his application but i couldn't get on a computer and was afraid that by the time i could get on a comp all the codes would be gone. so i wrote the code down and then went into the itunes store app, not the appstore. went to downloads and hit the redeem button and entered the code. I then got an error message saying couldnt connect to the itunes store and then it started loading and i got the picture attached. so basically you cant really download the app right onto ur ipod or iphone BUT you will have the application. and all you have to do is next time you go onto your computer just go to check for available downloads from the itunes store. so next time a dev posts a promo code for a free game and ur on ur ipod or iphone and ur like DARN! missed an oppurtunity to get a free game, think twice! lol EDIT: i just clciked on the appstore on my ipod and when i did that it popped up the account info for me to sign in and after i did that the application started downloading and now its on my ipod! so apparently you can use the promo codes on your ipod without even using a comp!
