Will I be able to access iCloud services on the web?
Yes. Web access to iCloud Mail, Contacts, Calendar, and Find My
iPhone will be available at icloud.com this fall.
If I use different accounts for iTunes and MobileMe, can I merge
them into a single account and use it with iCloud?
No. You cannot merge two accounts into one. However, you will be
able to move your MobileMe account ([email protected]) to iCloud
and, if you choose, you can continue to use a different iTunes
account for store purchases and iTunes in the Cloud.
