I had basically given up on trying to fix it. They are supposed to release a RUU for froyo here soon, and I was hoping that would fix the issue, then I could put cyanogen back on.
The RUU may not update the /misc partition which is where the problem is. Assuming there's not another carrier named Inland Cellular and your carrier's website is inland3g.com, then they do use Interop and your problem is probably the same as mine was. According to the "telephony.db" file from the generic CDMA 2.1 RUU for the HTC Hero, your CID is UTSI_016. This is a carrier ID assigned by UTStarcom for CDMA interoperability and shouldn't change between handset models. To fix this:
Follow the instructions I linked above.
When you do the "getprop ro.cid" make sure it's something other than "UTSI_016" to confirm this is the most likely culprit.
When you get to the hex editing step, also make sure the first 8 bytes aren't "UTSI_016".
If it is the same problem, your "getprop ro.cid" and first 8 bytes of misc.img will probably be "UTSI_005".
Correct the string to "UTSI_016" and follow the directions to flash the corrected misc.img back.
You do need to already have the right MMS server address and port settings for your carrier programmed. If you've been wrestling with this for a while, I figure you've already verified those.
We just stumbled on this last night and as far as I know I'm the only test case so far, so I can't take responsibility if you brick your phone. I'd suggest joining #unrevokedtest on irc.freenode.net for more assistance.
