Very Basic
here is a very basic one. it requires an IMAP account configured for your phone and your apple mail. if you don't use one with both, it won't do you any good. it is one way. it takes all the stickies, and sticks them in a mailbox called 'stickies' in your IMAP account. if you have a lot, it will take a little while, because apple mail is slow in creating mails with applescript.
try at your own risk. it hasn't been tested more than on my machine.
