iPhone generations, difference between 1st and 2nd gen
If one goes to the iPhone identification page of iFixit one finds 4 model numbers and iPhone generations
A1203 - 1st generation
A1241 - 3rd generation
A1303 - 3 Gs
A1332 - 4 G
Is there a second generation iphone? I have seen that descriptor before. What is the model number for the second generation?
