mail2web.com offers free email based on Microsoft Exchange. By “Exchange”, I also mean contacts and calendar synchronization. Webmail is through an ad-laden Outlook Web Access (OWA).
Note that this service doesn’t only apply to iPhones. It should integrate nicely with Windows Mobile phones. I’ll update this entry as soon as I have the time to boot up my old WM5 phone. If you dont have an iPhone or a WM, mail2web.com still will play nicely with your Outlook/Entourage.
Just configure your iPhone like this and you’re good to go. Be sure to select Microsoft Exchange from Settings -> Mail,Contacts,Calendars -> Add account…
Note: The server field should contain mobile.exchange.mail2webcom. Sorry about that
* FAST! Compared to Mobile Me’s “push” email, this one takes the cake. I use this email for email notifications from social networking sites.
* No server-side filters (like the ones in Yahoo! mail)
If you just want push email, mail2web is for you. Mobile Me is still nice, if you need a web gallery, iDisk, and if you dont mind shelling out $99/yr.
