Lol! The OS that comes on the phone should be 4.7.0.76. It's currently the most stable OS, but as you'll discover, it'll be nice when the official update comes out (just to make things faster/smoother), even though everything works as is!
As to trying out the leaked OSes and such, make sure you read all of the relevant BlackBerry 101s (like a lecture series/instruction manual), especially the ones on how to install the OS, how to fix a bricked BlackBerry, and how to use this great little program called jl_cmder (will help you wipe the OS off the phone if you need to start from scratch). Unfortunately, due to the nature of this forum, I'm not really sure how much more I can technically go into this. As to downloading applications, I haven't purchased any yet (waiting for the new OS), but I've downloaded a few free ones. For most of those, you can simply get them from the developer's site or by Googling the name (e.g. Viigo).
I hope you enjoy it and welcome to the happy world of crackberries! 
Feel free to ask if you have any other questions, and if you want, you can also check out the official BlackBerry Support Forums (also managed by the same people who do the Future Shop Forums - Lithium) over at http://supportforums.blackberry.com/rim/.
Kudos to you
. I had forgotten that Telus did have the ring option however did not know it would work on a mobile. I think 6 rings is the max as I did program *949, 6th ring voice mail kicks in. Well, yet to have missed a call. This sure helped. Am from Edmonton.
Just awaiting news on official release of the OS, hoping it to be a much improved version taking away the bugs. Did download Tiltris and Nintaii, got to level 6 on Nintaii, very addictive though finding sensitivity of the Accelerometer not so responsive. I suppose it could be me. Hoping that the new OS will probably correct that.
Am sure looking forward to Blackberry's App Store Front, it's exciting news for blackberry users.

Has anybody downloaded it yet?? I presume then this is final for a while.

That version is actually just 4.7.0.76, the original OS that the phones came with... When it says 4.7.0.109 in the forums, that's actually the package version.
But to make this really confusing, it sounds like the next leaked OS will actually be 4.7.0.109. Talk about confusing!
