MacRumors found some evidence, Apple might just be considering adding a free level of MobileMe service iDevice owners on iOS 4.2. “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.”

It looks like services include Find My iPhone, iDisk, Contact/Calendar/Safari/Notes over-the-air sync, and Photo Galleries might be free.
