Fix my ios code for a iphone/ipad game to make it compatible with ios 6+

I need someone to fix up my code for a small iphone/ipad game because my app won't validate in xcode since new apps now require some change to requesting UDID of users in ios 6+. Im not exactly sure what is causing the error but I know it has something to do with the "uniqueidentifier' being deprecated. So you must change the code and fix it so it can validate (you won't get the second half of the payment until it properly validates). You must also update the apps ad sdks and frameworks and make sure they still run properly. I know this a very easy small job for a good coder so it should take less than 30 mins.
