With the announcement of iCloud, Apple said a good bye to MobileMe service already but if you haven’t come to that point yet, it isn’t too late.
Apple had already made a statement in past where it stated-
“MobileMe is no longer accepting new subscribers. But if you’re a current member, you can still access everything as usual through June 30, 2012.”
Though the syncing service along with the iDisk and MobileMe app has already disappeared from the app store, your data is still accessible for a limited time as stated by Apple. Head over to MobileMe Homepage and take a backup of your data right away. Losing everything in your digital world and starting from the scratch would be the biggest nightmare for anyone has put efforts to keep their life more accessible and managed.
