yes the phone is unlock and i can dail phone calls . but when i try to connect to the internet it doesnt work

Is your Sony Ericsson network unlocked to accept the iPhone sim?If not, unlock it using the permanent unlock service from Prounlocking.com and once unlocked you can swap sim cards.BTW to connect the laptop to internet you can switch on the WiFi hotspot in your iPhone and scan for WiFi networks in your laptop and connect through that.
