I've been out of the smartphone app for a while (was there in the Symbian / J2ME days and in the early iPhone days though) but... I take it it's now legal according to Apple's term? Because IIRC there used to be (and maybe still is, but it doesn't look like it) an issue regarding generated code / automated porting tools for iOS? I think I remember it was a concern for people making tools allowing to do automated cross-platform porting to a variety of platform. If anyone knows/remember what I'm talking about and where the situation's at atm, don't hesitate to chime in and tell me when things changed or what I remember wrong.
