Yes, that's what I thought/hoped and I had tried doing that both with unlockit.co.nz (I understand there have been mixed results with the iPhone 4 - and have tried installing by email which worked for some - I show the installation, just doesn't work) and Apple's iPhone Configuration Utility (phone also shows the installation but, similarly, no joy - if I swap the card into a Sony Ericsson I do get data/mms - which are active with my carrier - PlusGSM). Reset seems the next logical step but who knows...
Got a tip for us?

Resolved!
posting what finally worked in my situation in case it might help someone else. Again, an ATT unlocked iphone 4 - everything worked except cellular data and mms. Under settings>general>network there was no field for "cellular data network" so I could not manually configure the carrier settings. This was why I was trying to force APN profile changes via unlockit.co.nz and Apple iPhone Configuration Utility. Checking with Tiny Umbrella/Cydia I had no saved SHSH blobs earlier than the current iOS so I was limited in risks that I could/would take as a restore was not an option. I had read about some having luck restoring data after doing a "reset network settings" but also read that this had relocked some unlocked phones. Reading the comments on one of these threads, I came across one that I was skeptical of (fortunately I was wrong) but seemed harmless enough to try:
go to settings>general>network then, with the phone on, eject the sim,
wait exactly 5 seconds and then reinsert (again, with the phone still on).
Much to my surprise, I now had settings>general>network>cellular data network.
I entered the carrier settings and now everything is fully functional
