Keep in mind that the 1st-gen iPhone only supported a small set of built-in apps. Third-party apps didn't appear until 2008.

HN discussion at the time:
- Apple iPhone SDK Event: iFund - $100 Million for iPhone Devs <https://news.ycombinator.com/item?id=130686>
And some early skepticism: "iPhone SDK And Restrictions: Some Of The Details Aren’t Great" (7 Mar 2008) <https://news.ycombinator.com/item?id=131171> Mostly concerns limitations on the API and what capabilities are exposed.
And for those who care to do more digging, a couple of searches bounded on 5 Mar 2008 -- 6 Mar 2012, the first 4 years of the App store:
"iphone sdk": <https://hn.algolia.com/?dateEnd=1331078400&dateRange=custom&...>
"iphone apps": <https://hn.algolia.com/?dateEnd=1331078400&dateRange=custom&...>
"iOS apps": <https://hn.algolia.com/?dateEnd=1331078400&dateRange=custom&...>
A very cursory eyeball of those shows some interest, but nothing overwhelmingly panglossian or critical. But I've not looked in depth.
