Well here's the condensed version of the email option.
First off, make sure you've got a good wifi connection. Test it by launching internet explorer and browsing a few pages.
Then go to a regular computer and get a new gmail acct, and use it only for people to send you mobile content like MMS. (Keep the new email address simple and short. Some folks without full keyboards have trouble entering characters into thier phones)
You'll have to tell gmail to allow pop access, just click the link I pasted below to find out how.
Go to your messaging application and click on Setup new email account. Fill in all your gmail information, and don't forget that your username must have @gmail.com at the end of it. If it asks you what connection to use select "The Internet" from the drop down box. Further instructions for setup of email can be found here...

Make sure you click on Pop Client Configuration List at the bottom of that link I posted to find out the proper server settings. Just use the ones for a standard outlook 2003 connection. Tell it to check for messages every 15, 10, 5 minutes, whatever you like.
You should be good to go! Just make sure you go into messaging again and select options, click your newly created gmail account and when you scroll through the pages that come up make sure you set the "check mail" option to manual if you plan on leaving the wifi connection so that it doesn't start up the cell connection.
