It really depends what type of game in my opinion (which sounds like your opinion too). I've found that RTS can get away with TCP. We used Apple's Game-Center matching for our iPad game (Stratosphere: Multiplayer Defense), and used "GKSendDataReliable" aka TCP.

It's real-time and works fine over 3G even... the real problem is having enough people online at once to even play multiplayer lol...
