All You Need to Know about iOS 7.0.2, in 45 Words
iOS 7.0.2 beefs up Passcode Lock security, eliminating access to the Camera Roll and recent apps, preventing non-emergency calls from being made at an iPhone’s Lock screen, and restoring a Greek keyboard for passcode entry. It’s a 21 MB download via Settings > General > Software Update.
It seems that this update also fixed the time and date stamp on messages. It has never been right until now.
I ran the update on my iPad 2 and it had no effect! It left my iPad running 7.0, but if I select Software Update in Settings, it tells me to download and install the update. I've done it twice now, to no effect.
