Apple will shut down its MobileMe service next month, but has extended its offer of an additional 20GB of free storage in iCloud until Sept. 30, reports “AppleInsider” (http://www.appleinsider.com).

Apple offered MobileMe subscribers the additional iCloud storage last year to convince customers to switch from the old to new service. At that time, users also received a free subscription to MobileMe until June 30, 2012, the service’s last day. However, that deadline has been extended by three months.
