My son has an old 1G iPod touch and we recently got a 2G for my daughter (no more fighting!). I would like to know if I can get away with buying the power support 2 pack for the 1G and using the second protector on the 2G touch? I understand the 2G's screen may be a bit wider, I have not been able to find any specifics on the glass size differences between the two models. Thanks!
