I work for a large software development company which only recently started development for iOS. We would like to be able to distribute a few of our apps without using iTunes as these are bespoke apps developed for other businesses. We currently do this using an Ad Hoc, but we now need to distribute the apps to over 200 iOS devices. The Ad Hoc will only allow 100 devices. Is there a upgrade to our account, or any other method I'm not aware of we could use?
