I have searched through the forum and I couldnt find answers to my questions, so her I go. I live in the UK and I made up my mind to buy the US version of N900.The problem is I dont know how it will function here.So if anyone of you who lives in the UK and has an US model can you please point me to the right direction.

Issues

1) Network: Will it work on UK networks especailly the 3UK sims?

2) Charging: Is there any difference in the hardware when it comes to charging the phone. I understand both these countries have different voltage supply and I dont want the phone to fry up

3) WIFI: are there any issues regarding this? frequency?channels?

4) Firmware : Is there any difference between the US and the UK firmwares.

I never bough a phone from overseas but i think I just got the perfect deal here. So please help me out
