Apple's iPhone software strategy moves me

A colleague scolded me for applauding during Apple's press conference to announce iPhone 2.0, next-generation firmware that will bring a host of enterprise features and support for a native software development kit (SDK) to iPhone and iPod touch. In my defense, I kept my pen and pad in my hands while the room went berserk over Apple's deal with Microsoft to bring an extraordinary array of Exchange Server connectivity to iPhone. I was moved, but not to clapping, by Apple's implementation of Cisco VPN compatibility, WPA2 security and other touches that IT administrators set as requirements for devices that connect to their networks. The enterprise half of Apple's new mobile strategy speaks to IT, and therefore to me as an IT journalist. iPhone 2.0 brings iPhone and iPod touch many steps closer to parity with the high-end BlackBerry, Windows Mobile and Nokia QWERTY and stylus handsets that are enterprise mainstays now. My journalist appreciates having a new contender in enterprise mobile, but does not applaud at press conferences presenting same. I nod and note.

But I am more than a journalist. I worked in engineering, consulting and technical management in the wireless industry before coming to InfoWorld. I've covered wireless, mobile and embedded technology during my entire tenure here simply by continuing to think and operate like a professional with skin in the mobile and embedded game. For over a decade, I've seen wireless carriers, hardware and component manufacturers and OS vendors come at custom software development from every imaginable angle but the right one. I've known for so many years that the barrier to a boom in mobile applications is a stable, simple, documented platform and a matched set of development tools. I've known that these things don't exist because no entity has found a way to make such an effort profitable. Apple has.

Lest I carry on too long in one post about a topic that will take many posts to cover, I'll clue you in on the points that provoked my applause.

Apple's native dev tools include live remote debugging and run-time profiling of USB-connected devices. During the demo, Apple showed Xcode's Instruments (formerly Xray, derived from Sun's DTrace) recording stack traces in real-time from software running on an iPhone. Developers of embedded software--and that's precisely what handset apps are--appreciate how difficult, expensive and tedious it is to design, code and debug with a tethered physical target, and what a big deal it is to have live debugging baked into an embedded platform and a free toolset. English translation: Applause.
