It doesn't seem to work - I put in the foreign SIM and can make and receive calls without an issue. But no 3G data available (and I have set all the data roaming, etc. on in settings). If I had root access, then I could try to flash that rom to see if it worked. I'm in South Africa on the Vodacom network (3G).
