iPad users - Really enjoying the new iPad. I've been successful tethering it to my iPhone 3G and using the internet with 3G speed. Although 3G speed is decent for many applications, I'd rather use a LAN network when available. I'd like to form an Adhoc wireless network where I work (no wireless available) and use the internet from a network cable plugged into my Windows laptop. Do you think I stand a chance? Anyone try this yet? Thanks.
