How does the SDK install apps on the iPhone

[maky29]

So I was thinking, if during development, one can install apps on the iPhone for testing without jailbreaking, why can't we use the SDK (or something similar) to transfer apps to the iPhone?

I agree that this would
1. Probably mean that jb developers would need to release source code, but I thought a lot of stuff is open source
2. Would be Mac only

Am I way off the mark here?

The SDK signs the apps and loads them on the phone just like iTunes does. You can't sign your own apps unless you have an SDK development license. It authorizes with Apple when you sign the application. Unless someone hexedits iTunes to stop authorizing, it won't happen.

Besides, pwning your phone is not a big deal and opens the phone up to a lot easier modification than with the work around you're proposing.

What is wrong with the current method?
