I installed mobilehotspot and left it on at work only to get a work mate thank me for allowing his iphone to surf my net all day. I had wep password but this did not work as I tested it again with a few other wifi devices and they could always connect to net and surf. I do have a moded Kernel and unsure if this was the reason as I have not seen any reports of this affecting the app...anyhow I just removed it and will wait for another option. It worked well apart from the security feature.
