Anyways, if you have read my blog recently and did follow what I did, you’d most likely already have your iPhone or iPad updated to iOS 4.2.1 GM. Technically speaking, it’s the same build of the latest official release of iOS 4.2 via iTunes today.
I figured that there’s no harm trying out iOS 4.2 GM on my iPhone. There’s always the option to restore it back to an older firmware using the recovery mode. So if you too can’t wait for the rumored 24th Nov for the official release, here’s how and why you should update it now!
