[QUOTE=SAR I;4187934]An exciting feature of iOS 5 is wi-fi sync.
If you have an old iPod Touch as your in-car audio solution, just keep the wi-fi turned on and merely "docking" your car in the garage gets all your new tunes in there without having to unplug it and dragging it to your computer. Couple of Smart Playlists and you won't even need to click a button in iTunes either.
Does iOS 5 get you Siri on the original iphone 4? Or will Siri only be available on the iphone 4S?
