I just had a technical question about the model no. and model id I was looking on wiki and looking at the model # and it listed mines as a MA610LL, thats comparing all the hardware and such taht came with the system with that on wiki. Then I saw another website that tells me where to find the model number on the macbook pro's body, which is on the underside next to some writing, but that model number comes out as A1211 So whats the difference between MA610LL and A1211, why are there to different numbers? I read on another website that one is referred to as the Apple Model No. and one is the Gestalt/Moded ID? Whats the difference between these two numbers and also, is this MA610LL listed anywhere on the computers body? if not where do you find it? Sorry for the random question just wondering what each means and what their meant to identify since they both describe the same model i guess? and where can the MA610LL part be found?
