Before them, phones used to be more or less open

Wow. Just… wow.

Excuse me while I get permission from sixteen levels of managers inside Cingular, U.S. Cellular, Cincinnati Bell, PrimeCo, and the fifty different regional carriers calling themselves "Cellular One" to offer my app on their networks.

I'm not claiming that iPhones are open to the extent that HN griefers want it to be, but you must have been freshly hatched in the years before the iPhone to think the ecosystem was open.

I say this as someone who developed some of the first mobile phone weather apps. (Before "app" was even a word.)
