I would need to check on the exact version but it is the new one that came out for the Nextel 7520 and I have to apologize not realizing that there were a pack of wolves posting here
as long as it helps, it is directed to both of you. The version for the BB is 4.0.2.37 and the Desktop software is 4.0.1.10 and this is for the 7520 on Nextel
