Upgrade to 1.6

[lang94]

I just got this phone yesterday. My phone is sick of my old LG vivaz Pro not being able to pick up calls, and cause my contract is over in 5 months. she went with a relatively cheap phone.
This is my first android phone , so I dunno how to upgrade this to android 1.6. From my research, there is a lot of controversies :O . and it seems that 1.6 is latest version. but I dunno how I can upgrade to that?I don't run on Tmobile, the network is FIDO , in canada LOL
Also, what is rooting? heard that a lot but I have no idea

thankss
