Be gentle folks, this is my first post. The IPad looks and sounds great!!! I am a serious user (not a techie) and feel frustrated that this great new gyzmo won't easily replace a laptop - but the reader looks great and the carrying weight is a huge appeal. Enough preamble. I have an idea for a clever person(s) to create a money making App for the iPad. Don't know if the technology is possible but the idea seems sound. Hear me out. We really don't want yet another telco contract just to get a SIM card. WiFi is fine, 3G SIM is fine in home country. But there are occasions when getting on line is a must. So, the question / idea? Can someone create an App that tethers (if that's the right expression) or WiFi links your Ipad to your iPhone so that the iPad can connect using the phones 3G connection? If the technology is possible, there's money to be made.
