The above message has been posted to the .Mac Tips website. As you can see .Mac members are being told to sync their .Mac bookmarks to a computer (Mac or PC) by July 6th because web access to bookmarks is no longer going to be supported in MobileMe (.Mac’s replacement). The July 6th date is actually a few days later than the one Apple first gave in this KB article (June 30th). It looks like Apple wants to give all .Mac members as much time as possible to get their bookmarks in order.
Does this mean we’ll see the official launch of MobileMe on the 6th? Probably not, since Apple has stated that MobileMe will be available on July 11, but then again Me.com email is already being properly routed so this might all be part of a soft launch (as they say in the biz).
