Apple offered 30-day extension eligibility for MobileMe subscription members, after some unexpected issues came to light during last week’s launch. The company said the transition from .Mac to MobileMe was “a lot rockier” than they had expected and that customers will benefit from the free of charge subscription while they wait for the transition period to end.

Customers who were .Mac members with active accounts as of July 9, 2008 and new MobileMe members who created an account on or before July 15, 2008 will benefit from the 30-day extension, which should be applied to their accounts within the next few weeks, Apple announced its customers.

“Although core services such as Mail, iDisk, Sync, Back to My PC, and Gallery went relatively smoothly, the new MobileMe web applications had lots of problems initially. Fortunately, we have worked through those problems and the web apps are now up and running,” Apple said in the e-mail sent to its customers.

Another problem on the agenda was the use of the word “push” that many rejected. Many users have complained about the fact that it took up to 15 minutes to sync with the MobileMe cloud. Apple answered in the same e-mail that they are going to stop using the word “push” until the sync is “near-instant” on PCs and Macs.”

MobileMe was created as a new Internet service that delivers “push” (or maybe not exactly push…still remains uncertain) email, contacts and calendars from the MobileMe service in the “cloud” to native application on the iPhone, iPod touch, Macs and PCs.

Apple introduced MobileMe as an Internet service that “takes the best of .Mac,” while at the same time adding many other new features. Compared to the .Mac, users are now offered double the storage. However, some of the .Mac features were discontinued: Web access to bookmarks, iCards, .Mac slides, and support for Mac OS X 10.3 Panther sync.

MobileMe became available on July 11 as a subscription-based service, with 20GB of storage for $99 per year for individuals and $149 per year for Family Pack.
