iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple to Offer Free MobileMe Service to Some iOS Users?
New evidence uncovered in recent iOS 4.2 builds and the iOS 4.2.1 golden master seed is suggesting, however, that Apple will be offering a free MobileMe tier to users. The evidence comes in the form of a new private framework known as AppleAccounts.framework that includes a series of device-specific error messages referring to free MobileMe accounts. In particular, the error messages include alerts regarding having reached "the maximum number of free accounts" for a given device and certain devices not being "qualified for free MobileMe service".
The framework has been localized for dozens of languages and countries, and is not present in the currently-shipping iOS 4.1. Meanwhile, an error message in another part of iOS suggests that free accounts may be used for features other than email, as an error message specifically restricts certain Apple IDs from being used with MobileMe Mail:
"This Apple ID cannot be used for MobileMe Mail, but you can use it for other MobileMe services."Other MobileMe iPhone services include Find My iPhone, iDisk, Contact/Calendar/Safari/Notes over-the-air sync, and Photo Galleries.
This might fit nicely with a previously unconfirmed rumor that Apple would begin offering MobileMe syncing services for free. Over-the-air syncing has been an area where iOS has lagged in comparison to Google's Android operating system.
