okay so I was thinking of buying the beserker booster upgrade for mybrute which is $0.99. I installed MyBrute on my brother's iTouch and mine, and we use the same itunes account. Its basically two different iPods, but the same account. If I buy the in-app purchase on my itouch, and then go on my brother's itouch and press " restore in- app purchases" will my brother and I both be able to use the upgrade? thanks, and sorry if it's confusing haha.
