The overwhelming majority of games are already 3.0 compatible. I think you're asking more of, what games are ready to use the new 3.0 APIs. That's fairly obvious, especially Push. Beejive, IM+, Tweetie (and all Twitter and IM clients). Lots of games will use microtransactions, and the other things. Like the rumble API sounds nice. It's just a question of when. I'm hoping that Beejive is ready on day 1, but probably not.
ive recently seen a lot of updates just saying that they are now OS 3.0 compatible so id say that most apps at this point are indeed OS 3.0 compatible
I'm far more concern about what's is NOT compatible rather than what is compatible with 3.0 when considering about upgrading.
yea your right i looked up all my apps to check wether they were 3.0 compatible because i dont want to upgrade and not be able to play my best games because they dont work with 3.0
Amazon Mobile has a glitch on 3.0 that makes searching almost impossible Symbolism won't let you use Open Feint @goldglover: All apps are being tested with 3.0 right now. I don't just mean new games either, ALL games on the app store are being tested with 3.0. Any game that fails to work on it will be removed from the appstore until it is updated.
