I am guessing this is just a blank .ipcc that enables those options in the Settings. I remember playing around with the values in the old ipcc, settings values from '0' to '1' used to enable MMS in the Cellular Data tab...
It probably is, the download is something like 60k, it is very small. But on the other hand, I would think Apple would make it a bit more 'Difficult' to enable MMS on a 2g than just the IPCC files if they REALLY REALLY didn't want us using MMS?
