I am currently trying to configure NetShare again. I don't want to buy PDAnet (I'm cheap) and I don't want to jailbreak (I'm lazy). I've configured my Macbook Air according to the instructions found in the NetShare Application and the iPhone is also configured according to the instructions in the NetShare application. The 2.2 firmware seems to have a problem with ad-hoc wifi. I can put the IP into the "Static" menu after connecting to the ad-hoc wifi network on the Macbook Air, but the iPhone refuses to remember the information no matter what information is entered into it. Does anyone have any ideas on what I could do to correct this?
