I'm not sure how. iPhone was available in June 2007. Android went into public beta in November 2007, and reached 1.0 and was first released in a commercial device in September 2008. [1]
I guess Android, or what morphed into Android, was probably being developed, in a pre-beta state, when iPhone was announced in January 2007. Okay. It sounded to me like someone was saying that Android was released on Blackberry-like phones at the time iPhone came out. That was only thing i was objecting to. Sorry, a small point I almost didn't even bother to make, and probably not helpful to anybody, anyway.
