Here is a little tip for all of you there new to iPhone on O2. Until now we've had email on our other phones but it has never been as usable as it is now on iphone. This means that if you regularly read email on your iphone , you don't want to read it again on your computer. so, use IMAP email. not POP3 Great thing about IMAP is that it automaticly syncs all your email to your phone and your mac ..so if you've read email on your phone it will not show as unread on your mac. Gmail is also great because you can create "notes" in your Mail.app and they will be automatically synced to your iphone. If your current service provider does not provide you with IMAP email service, time is now to start using GMAIL. If you are using Gmail already, read this guide to enable IMAP email http://5thirtyone.com/archives/862 Don't have a gmail account? Step by step: 1. Sign up to Gmail 2.

In Gmail settings/accounts add your other email address so when you send email via gmail the "from" is still your old email. 4. Set up IMAP gmail on your Mac and your Iphone. see guide here: http://5thirtyone.com/archives/862 you are all done. Welcome to 21st century email.
