Has anyone been able to verify that the iPad cannot create an ad hoc network?
It has different radio hardware (the fact that it does 802.11n demonstrates this) than the iPhones, which I thought was the reason that the iPhones could not create WiFi networks.
I know this was sort of answered elsewhere, but I wanted it to get proper attention with its own question and by more tag coverage.
Jeff, your god of biscuits. ;)
Wanted to update this question: as of iOS 7, the Multipeer Connectivity Framework provides a very high level means of establishing ad-hoc networks via WiFi and/or Bluetooth. It even bridges from WiFi from/to Bluetooth if some ad-hoc network clients have WiFi off and some have Bluetooth off.
