Twitter notification, which looks pretty similar to the messages that you get when the wireless hotspot function is active. Even though we are not exactly Photoshop experts, the leaked image appears to be unaltered and this may very well be the way notifications and status updates are going to work in iOS 5.
The second image that we are dealing with is a screen grab from iTunes and hints that wireless software updates may come with iOS 5 in one form or another. Apparently, somebody was digging for app updates when they came across a page in iTunes that mentioned an Automatic Download function, which does not exist in iOS at this time. It appears that having the alleged iOS 5 function enabled will let you get software updates automatically, but some also suggest that it might be capable of updating your device's firmware as well. Even though the revealing line of text has been taken out by Apple already, others have also managed to snap a screenshot while it was still there, so it isn't very likely for the clue to be faked.
All rumors will be debunked shortly after WWDC takes off so stay tuned for our coverage. The event is scheduled to begin today at 10:00 AM PDT.
