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!!
