Thanks for this... so it sounds like I will no longer be able to use my .mac account for email or anything else.
A couple of days ago I bought an app from the app store only to find out that I couldn't download it onto my iPod Touch because I didn't have the latest iOS. And I couldn't upgrade because I couldn't upgrade iTunes, because I couldn't upgrade my OS. So this raises another question, which is: without iCloud, will I not be able to sync any devices any more?
Or am I left in No Man's Land waiting to get rained on by the Cloud?
Humm, you can, at least via browser...mobileme will last till 30 June 2012 , then it will be upgraded to iCloud.
Till then you have time to find a solution...
MobileMe Mail => lots of free solutions, Gmail Included.Or You can try configuring it manually, like the the hack for contacts and calendars.
Contacts => You can try the hack for snow leopard, maybe it will work on leopard.I think what the hack does is just giving you the "manual" configs, so maybe it will be OS indeppendent.Or use google contacts or another.
Calendar => Try to configure it manually, although I guess this can be more complicated.You have google calendar.
iDisk => you have dropbox and others, and you have
this program.
Gallery => you can use,flickr or picasa.
About your iOs devices, if you have leopard I guess you can update it (I'm not into it), from what I know only tiger is left with outdated itunes.
