I updated to the most current version of iTunes, plugged in my iPad, clicked check for updates and got the following message "iOS 4.2 is the current version". When I went to update my iPhone 4 it immediately notified me that 4.3 is out and asked if I'd like to update. I ended up having to download the 4.3 ispw to my desktop and manually locating the file to update. Anyone know why this happened?
