Help!!! (dont even know what else to put here)

Hey there,
I live in Toronto, Canada. I have a W580i locked to Rogers' network.
Recently my girlfriend asked me to buy her the same phone but in red, but the catch is she is with Fido(another cell phone carrier), which meant I needed to buy a unlocked cell phone (local trade).
So I found this one, which I think is W580c (the Chinese verison?). Anyway the guy I bought it from told me he got it from Honk Kong.
Now the problem I have with it is that it has this whole chinese menu, like the interent browser, or some other chinese apps (the phone language is English though) and I was wondering if there is a way to change it to a North American or at least International firmware? I have bunch of Chinese games, themes (in Chinese) which I dont need. I have never experimented and have no idea how to do anything of this sort with my phone and really need some help.
TIA, and have a wonderful day!

First of all, download SeTool2lite 1.11 and post an identify log(without IMEI):
How To Post An Identify Log? - Top Sony Forums

i tired googling it. couldnt find the SeTool2lite 1.11.

TIA

Try to google "Setool2lite V1.11.rar".

ok. you gonna think Im a complete noob, but i have done my best. searched every torrent site. nothing real. its either not downloading due to low seeding, or pass protected.
TIA
