"We've been waiting for MobileMe to go free for a while now so we're not holding our breath, but could iOS 4.2 really, finally bring a free MobileMe tier to users? MacRumors has found evidence in AppleAccounts.framework that suggests yes."
I've heard rumors about a free MobileMe service a few times this past year. Looking at the same framework file that MacRumors looked at, you can see the the paid MobileMe service isn't going away, at least anytime soon. I suspect what we're going to see is a free version of MobileMe that allows syncing of calendars and contacts, and possibly the find my iPhone feature, but doesn't provide a .me email address or online storage. Personally, one of the reasons I use MobileMe is that with a paid email service, I don't have to worry about my mail being read by robots to serve me targeted ads. I'd hate to have that go away. Do you think Apple is going to be giving MobileMe away for free?
