iOS 5.0 SDK - USB host OTG

Question

I would like to connect to the iPhone a device that was not manufactured specifically for the iPhone. It can be accessed from a PC through USB, so what I'd like to do is connect it through an iPhone dock connector-USB adaptor. I am aware of the previous questions regarding this topic but most of them seem outdated.

1. Can it be done in the newest iOS SDK (5.0 or higher)? (If no, can I dit it with a jailbroken iPhone?)
2. Are there any limitations?
3. Do I have to join the MFI program? AFAIK, MFI program is aimed at companies that are creating hardware components together with the software.

Answer 1

You should be able to do it with a jailbroken phone.

Otherwise you would have to join the MFI, and it would additionally require custom hardware on the device.
