BB Tour :: Unlocked 9630 Won't Connect To BIS

I had a Blackberry Tour 9630 (sprint) that got stolen while in Slovenia. I ordered a replacement from sprint (same Tour 9630) and they neglected to tell me that the phone must be activated before it was sent out to me. So, I receive the phone and the SIM card and spend about 3 hours on the phone with Sprint customer service trying to get BIS services to work. Voice services work just fine but BIS services don't work at all. I confirm that BIS is activated on my phone and international roaming is active, check on both.So after hours on the phone they come to the conclusion that the phone needed to be activated in the US before it was shipped out to me. I then go another route, knowing that my phone is unlocked, {SIM, network, network subnet, service provider, and corporate} all say "disabled", and try to use my Slovenian SIM card (SI MOBIL) with BIS services activated and still only voice. I even try the Slovenian SIM card in a colleague's blackberry and it works just fine.
