After 4 days you will be able to install the new version of iOS on your iPhone 4 , iPhone 3GS , iPhone 3G , as well as on the iPod Touch 2G and 3G, we already showed you yesterday the significant improvement in iOS 4.1 in a speed test video on iPhone 3G.
Important note: If you have a jailbreak or unlock for your device please keep away from upgrading to the new iOS 4.1, until jailbreak and unlock tools are available.
