Fixing MMS on Dell Venue Pro

Symptoms:

1. You forced the Mango updated on your Dell Venue Pro. (Here's a page with instructions if you haven't seen it yet: http://www.wpcentral.com/force-mango-update-early-through-zune-software)
2. Someone sends you a text message with an image.
3. When you click the "Get media content now" link, the message flickers but you don't see the image.

Problem:

The "MMS Proxy" setting s was erased from your phone when you applied the software update.

 

Solution:

1. Dial the number ##634# to launch the diagnostics page.
2. Go to "MMS Settings"
3. After the Mango update, all of these fields were blank for me.
4. Click the "Restore system defaults" button.
5. You'll get a "Success, Setting is Done!" message.
6. You'll see your carrier's values in the text boxes.
7. Now go back to the messaging app and you should see the images when you click the "Get media content now" link.
