How do I install IPA on iPhone without iTunes from Windows

Question

How would someone install an iPhone app (.IPA) on an iPhone without a Mac or the use of iTunes? Also, if this wasn't already difficult enough, I don't have access to the iPhone. I can get the app to the person whom will be testing the app but I have no access to the device it will be installed on or a Mac to distribute the application.

Answer 1

I know four options for this:

1. Using iTunes (Install the utility and copy the app)
2. iFunbox (Install the utility and copy the app)
3. iTools (Install utility --> Goto Application Tab --> Click on Install --> select application and it will be installed)
4. Online Method: Diawi (Upload the IPA and open the URL on device to install IPA)

Answer 2

Easiest way is to use a platform like HockeyApp. Create an account (10 apps are free), upload it and tell the link.
