Flexible Cameras for use with Iphone

[Kenwc]

I'd like to find a good flexible camera that interfaces to an IPhone or Ipad.

I've seen one style that has to be connected to the device and another that is WIFI that can be used separate from the device.

Anyone here use these and have any recommendations?

I'm also curious, although I'm an Android phone and tablet guy.
