Where can I find the IPhone SDK prior to version 3.0?

do u mean a power core like a g4? intel based are the new ones and i would ume the sdk 3.0 would have been desgned for the intel mac. anyway if the apple site doesnt have it, send them an email asking for help, and if all else fails try to get a torrent. btw you fo realise the iphone sdk cost money
