iOS 5 expected to make debut in September.
iOS 5 might be the talk of the town right now. But Apple has just released its latest version of iOS 4. iOS 4.3.5 doesn’t offer a major boost, but offers beefed up security for the iPhone and iPad.
The security issue relates to certificate chain validation and the update is advisable for all iOS users. The software boost works on the iPhone 4, iPhone 3GS, both the iPad and iPad 2 and the third and fourth generation iPod touch.
This will likely be one of the last updates to iOS before the big release of iOS 5 in the next few months. That change will bring improved notifications and deep Twitter integration to the mix.
