Amazon is apparently preparing my order for shipping and I will be recieving my first ever Ipod Touch soon I have always had my Imac plugged directly into my DSL modem, which has wireless capability but I have never used it. The airport on my mac detects it as an open wireless port with no security...but I leave airport turned off. How dangerous...security wise...is it to just let the touch link with the open signal of my DSL modem if I am just doing general internet surfing? I was thinking about doing an internet sharing setting through the Imac with WEP security since I found something about that in the settings...but someone talked about trying that in the apple forums and it did not seem to work. Obviously I am a wireless NOOB and I don't really want to buy a router. I figure I can go the computer if I am going to banking or something that needs to be secure. Thoughts???
