Some definitions

  • [mySTEP] is the GNUstep based GUI toolkit (i.e. frameworks) extended by QuantumSTEP (which adds an application suite e.g. for address book, calendar, mail, etc.) to develop applications for Linux/X11 based handheld devices (i.e. Sharp Zaurus, OpenMoko Phone)
  • iPhone SDK is the Apple SDK to develop native applications for the iPhone and the iPod Touch
