Getting a new HTC Desire HD

[Perito]

hello,
I'm going to buy a HTC Desire HD phone on Monday. I wanted to ask what is the latest OS on that device (leak or official)? Where can I download it?

Also, what are the "must" applications for such a device? I'm a blackberry owner and this is the first time I switch to andriod so I'm confused as to what applications I must have on my phone. (By must, I mean top ranking application that are generally used)

Thanks !

The official OS is 2.2 which will be installed, the updates aren't like the Blackberry's where you can download from a provider as far as I know any updates are OTA. Regarding Apps been an Android user with a Desire HD for one and a half weeks I cant really be helpful as im still feeling my way as well.
