Sorry for the total noob question ..... but I have a rare user in Canada with a 6750 on Aliant (New Brunswick Canada). I've never dealt with this model or this provider. Their web site is not helpful and I can't figure out if I can upgrade this unit to v4. It currently has net_rim=3.6.1.21 and platform=1.2.0.6.1.

If it is possible to upgrade the OS to v4, where do I download it at? I couldn't find anything on aliant.net.

Thanks for any help!!

Unfortunately not, I think 3.6.1.41 is that max OS at this point.

Finch is correct: No version 4.0 for this model.
