Because Angry Birds a heavy weight PhysX game run on 1st GEN, according to iTunes specs.

What i need to do ? limit to 2nd GEN ? 3rd GEN ?

I have only these two devices iPhone 3GS ARMv7 and MOTO DEFY ARMv7.

I would limit your apps to Touch 2G and above, if you can. I have a Touch 2G (as well as a Touch 4G and iPad2) and I would consider the Touch 2G the *slowest* possible device I'd test against. I wonder how many people even own a Touch 1G anymore...

And while Angry Birds "runs" on a Touch 2G, it isn't great. It bogs down when there's more-than-average number of physics objects, it takes a long time to load the app, and basically the performance is "acceptable" but that's all I'd credit it. If Rovio is claiming 1G compatibility, they're stretching the definition of "compatible".
