NullRiver released NetShare, a tethering app, in the iTunes App Store only to have it pulled after a few minutes. the app would have allowed iPhone owners to share their mobile internet connection with their laptop.
Yeah we know, it would have been great.
NullRiver states on their website that they haven't received any word from Apple on why the app was pulled from the store, and that the app doesn't violate any developer or App Store agreements.
"Furthermore, plans(unless specifically designated for tethering usage) cannot be used for any applications that tether the device (through use of, including without limitation, connection kits, other phone/PDA-to computer accessories, Bluetooth® or any other wireless technology) to Personal Computers (including without limitation, laptops), or other equipment for any purpose."
Nullriver hopes that Apple will release the app in countries without tethering restrictions in their mobile contracts.
