i will show you an alternative to using stickies and notes. it also allows syncing between your iphone and your mac
they are simple to use, they sync with each other. its free. all notes are editable!!!!!
ive been using both for a week. this post was written using simplenote, when I had some free time on the train. there are a couple of clients for your mac, I chose Justnotes.
you will need a simplenotes account (you can create one when you open the iphone app) – once its setup your notes sync to the cloud automaticaly and are available on your mac and your iphone – no more mailing yourself todo lists – simply create them on your iphone (or your mac) and edit them as you do things =)
