QNX 6.2.0 vs. 6.2.1


some months ago I managed to install QNX 6.2.0 on my machine. The software
installer never gave the opportunity to choose a www repository. Don’t know
why. So I’d like to install version 6.2.1 . But right now I can’t find a way
through the different versions and patches.

Can anybody help me finding a 6.2.1 image for download and burning on cd?
What is necessary to get the latest patch for it, afterwards?
