So, it's not yet unlocked from Sprint? Please carefully double check via the link provided in post 2 above. What you describe does not match what I understand for the unlocking procedure...
FYI...I've never seen a 6 digit unlock code...the last one I used was 16 digits long...doesn't mean this 6 digit code you have is not right, just that it's something I've not seen. Further, nothing about the unlocking procedure as I understand it (also in that linked post above) presents the screens you are indicating. Hence, I have to wonder if the thing you are doing is something separate from truly unlocking, and rather a programming screen to do some things...but it would likely have as a prerequisite that the device already be unlocked from Sprint (as per that above procedure).
Also, just to reiterate, it matters not which carrier your OS package comes from...just that it be specific to your BB model number. Indeed, I'd highly recommend that you revert back to a higher level...the version you are now running is well behind what would be considered current, and may well have bugs and such that are fixed in later versions.
What I have for simulator is 188.8.131.526 from Sprint (sorry, I don't track those "bundle" numbers but rather the true 4 octet OS level). But, from what you've described, I don't think I can simulate any of that anyway.
Good luck and let us know!
