iPhone Refund Policy is scary
Of course I just signed up as an iPhone developer last week. Sigh. I actually took the time to read (most of) the contract, it's mostly blah blah blah and things I already knew about, but I didn't notice that part.
That's a seriously terrible policy, which I'm guessing is a response to the Android app return policy.
Basically you shouldn't spend too much of the money Apple gives you until it's from sales 90 days old or older.
