Why should I upgrade my iPhone 4 to IOS5?
rtrembley 2 years ago
Apple is promoting a new version of the iPhone operating system, IOS5 which is due in a month. When IOS4 came out, it could be installed on older iPhones, slowing them down, and making them more difficult to use. Why would I want to upgrade my iPhone 4 to IOS5? Will it slow my phone down? Will I be able to retrograde back to the current version (IOS 4.2)?
