i had issue before ! fixed. make sure log out of app store regular account , itunes.

next time test iap on device, log in sandbox account. should work.

also, if doesn't fix problem, have @ this: my iap isn't working. bugs @ func paymentqueue

it contains code iaps (which works) , tips fix issues. hope answer helpful ;)
