Months of beta testing and waiting have finally culminated with today’s highly anticipated release of iOS 9, which brings users a smarter Siri, better multitasking on iPad, speedy UI improvements and all-around better performance.
Apple just made iOS 9 available to iPhone, iPad and iPod touch users. The new mobile OS, which promises to be significantly smaller than previous iOS upgrades, can be downloaded via an over-the-air update — but the smart move is probably to use iTunes. (After backing up all your data, naturally.)
Some users are experiencing problems with the over-the-air update, but if you want to try that route on your iPhone, iPad or iPod touch, all you have to do is go to General >> Software Update.
Apple Support’s Twitter account notes that some users may have a hard time upgrading to the new iOS 9 update because demand is crushing their servers. iTunes downloads appear to be working for most users, though. Other users have had better luck after rebooting their devices.
IMPORTANT NOTE: Please be patient w/ #iOS9 as due to the overwhelming numbers of downloads, it may not download right away. Thanks!
