Just wondering: if I paid the $99 bucks to become an Apple Developer, could I write and then self-sign a tethering app that would run on my phone (without jail breaking)?
Others have answered that this is technically possible. I'm guessing, however, that it would violate your agreement with either Apple or your mobile carrier. Since there are lots of mobile carriers, does anyone know whether it would violate Apple's developer agreement?
I am going to say yes, I am also sure there are sourced tethering ios apps out there.
Yes, that would work.
Don't self-signed apps expire in three months? If yes, it would be really inconvenient.
