Apple’s upcoming MobileMe service, replacing the existing .Mac offering, has yet to be released. However, some users are reporting proper e-mail forwarding with the @Me.com alias.
I confirmed this with my own .Mac account. This morning, a test email sent to “ @Me.com” was correctly forwarded to my current .Mac inbox.
The complete transition of to MobileMe is expected to occur sometime around July 11th to coincide with the release of the Apple iPhone 3G.
