Might be an odd question but...
Is there an app to turn my phone into a wifi connection for my existing newtwork?
I would like (if possible) to connect my DS to my current wifi (wpa) network, through my phone, which would be set up as wep. That way I wouldn't have to mess with my network at all, just run the app, have the phone connect to my wifi and route any connections it receives through the existing network.
Does such an app exist? (even an iDevice app would do.)
