Is there any way which we could get connected to Internet via a mobile phone?

you need a bluetooth dongle and a GPRS connection on the phone.

I don't know how it's done. but U only can access mobile websites

u can visit any site;u can connect using ur phone's gprs modem by dialling *99# on dialup connections,select ur phone as modem,

i'm using a slot10 gprs modem and can download about ~4-5kbps,
machan but this will cost u a lot,just use ADSL,it's the cheapest
