-The 2nd generation comes in 8,16, and 32gb models and the 3rd comes with 8, 32, and 64gb -2nd gen iOS is up to 4.2, 3rd gen iOS can do OS 5 and beyond. -3rd gen seems to be faster than the 2nd gen (don't get a 8gb model 3rd gen. they just rip you off and actually give you a 2nd gen model. 3rd gen 8gb IS the 2nd gen 8gb.)
