SwirlySpace, the guys who brought us the
MMS app back in December, have updated to version 0.3, which now lets you
receive MMS!
This is "very rough" according to them, but a new version will be released soon after which will be much more polished. The good news is - it works. MMS receiving on the iPhone! It should appear on Installer within 24 hours.

You can add this from Swirly's source until Ste gets it up -
swirlyspace.com/SwirlySpace.xml and add version 0.3.2.
