You just need to call Cox and talk to technical support and tell them you just bought a new modem. They will ask for the MAC address and Serial Number which will be on a tag on the modem and probably on the box too.
lol Rakeesh you bastage! Siri seems to be a lot quicker with ios 6
My boss gave me an iPad (the most expensive model you can buy in fact, typing on it right now) and I tried siri...it just doesn't even compare to google's. I don't really use either though, especially on android because swype is so nice, and I don't particularly like having a conversation with a computer.
