I have agk, but its not for agk testing. You cant test a game downloaded from the store in the simulator. Android simulator works like sludge, you need an actual device, as otherwise the speed is WAY too slow to be useable.
You are right about ios devices dying out, my ipod touch will not work on new games, because they use ios6+ my ipod touch only goes up to ios 5, so thats that device finished. Same goes for my mac, cant run the new xcode, I think its sdk5+, so that makes problems, its just a racket with these companies. Its called 'planned obsolescence' for maximium profits.
