I have bought an Android phone Spice MI-270. I wanted to connect the phone to Linux Fedora so that I can browse the web using the services provided on my SIM card. How can I connect the Android phone to Linux Fedora to use the Internet ?

If your question is rather the other way around: Your laptop having internet, and you want to use that connection from your Android, this is called Reverse tethering. In this case check:
