The upcoming iOS 5 update announced by Apple recently, will address a few different issues; rectifying the software glitch that has caused battery life problems is certainly one of the top priorities, but there are also some security flaws waiting to be solved.
Many users complained that battery problems had surfaced with their iPhone 3GS and iPhone 4 handsets when they upgraded to iOS 5, whilst iPhone 4S owners claimed they were getting less than the life advertised.

The magnetic covers proved to be not so smart as they allowed nosy intruders to access the locked iPad 2. Basically the Smart Cover unlocks an iPad without requiring a password, and allows access to the last screen the user left open before the iPad went to sleep.
This will be changed with the next iOS 5 update, based on the iOS 5.0.1 beta recently released to developers. The full update should be available to users within a few weeks according to 9to5Mac.
