ICloud – Why do i need a new email account to sync the notes in iCloud

Syncing the notes to your computer, then moving the notes to your email notes and letting it sync back to the phone would be the easiest.

Without syncing you could email each note to yourself by clicking the envelope icon at the bottom of each note. Then turn it into a note in your email account, of course this would take a long time but you wouldn't have to sync with your computer.

Practically speaking, the answer would be no - iCloud doesn't "sync" multiple email accounts (this is built into iOS). @me.com email address is just like gmail - it is just another email account. If you really wanted to, you could have all your gmail forward to iCloud's @me.com email account, but that wouldn't be practical.

To have your Gmail accounts synced into your iPad, open Settings, on your iPad, tap Mail, Contacts, Calendars, select Add Account, for a Gmail account select Gmail, and enter your information in there. Repeat the process for every mail account you have. (You should notice your iCloud account in the list of email accounts when you first open it)
