Latest redsn0w http://is.gd/buMgi should fix any APN/MMS issues (remember to deselect Cydia if it's already installed)




EDIT:

Apple has released OS 4.0.1 to address signal calculation issues for the iPhone 3G/3GS/4.

Redsn0w and Ultrasn0w will still work

After you update to OS 4.0.1 you can use redsn0w 0.9.5 to jailbreak 4.0.1 on iPhone3G. Just point it at the 4.0 IPSW

(Yes – point it at the 4.0 IPSW even though you're at 4.0.1).

This will also hacktivate your iPhone3G at 4.0.1 if you haven't already been activated by iTunes. Install ultrasn0w if you need a carrier unlock (and in the USA, remember to turn off 3G mode in Settings→General→Network).

I am using the following settings and cannot receive MMS. I can send but not receive. If I use epc.tmobile.com, then I cannot access the web over EDGE. Any ideas?

To all who are still trying to get MMS on iOS 4 working. I finally got MMS working on my iPhone 3G using the following method and settings:

I jailbroke using redsnow 0.95.5b5-5.
I unlocked using ultrasnow in Cydia.

I installed the T-Mobile 4.0 MMS Fix in Cydia from the following repository, http://beta.leimobile.com/repo/

Lastly, I am using the following settings:

Enable 3G: Off
Cellular Data: On
Data Roaming: On
Internet Tethering: Off
