I downloaded xcode sdk as "xcode_4.2_and_ios_5_sdk_for_snow_leopard.dmg" and try to install it on my mac mini Mac OSX v 10.6.4 Snow Leopard. But when I stated installation this gives error that minium mac OSX v 10.6.7. Please tell me how to upgrade it 10.6.4 to 10.6.7 for free. Or how to install it directly. In my system XCode previous version 3.2.4 is install. and it supports only iOS 4.1. I want to work on iOS 5.
App Store's updates and update it. It'll download a new install file(near 2.0G) for you. - Kjuly
