In case you’re sleeping last night ( I was!), you might have missed the announcement regarding the availability of iOS 4.2. This was a big news last night in the U.S. Check out Techmeme and you’d see how many tech blogs have covered it. Anyway, well yes! iOS 4.2 is now out and you can update your iOS devices – iPhone 4, iPhone 3G, iPhone 3GS, iPod Touch 2nd to 4th gen, and of course the iPad.
It’s a major update, so download will take quite awhile. Exercise patience at all cost. As a reminder be sure to back up your iDevice before updating. Update for the iPhone 4 is around 650MB while for the iPad it’s around 550MB. To know more about iOS 4.2 on iPad, check out these post.
