Hello everyone,
As the tile says, I'm new here and new on Android.
I'm quite used to windows mobile, have used it for many years and decided it's time to try something new.
So I bought myself a new toy: the HTC HERO.
Like it so far but it's quite disconcerting... Read everywhere that there is a new version android 1.6 available. I tried to read as much as possible and still don't get it

Here we go:
It seems my Hero is firmawre 1.5. Do I need to upgrade to 1.6?
If yes, how do I do this?
I tried to go on the android market to download a few apps. No success with my PC, no success with my Hero in wifi. It it absolutely neccessary to do this using 3g with the Hero?
Thank you very much for your help, and sorry if this has been asked already elsewhere on the forum, couldn't find it.
Take care.
