For the last week or so I've been beta testing a well known iPhone application. Beta testing involves using the 100 iPhone "Ad Hoc" distribution method first outlined at WWDC 2008. I was planning on writing up the process, and my experiences being involved in it (all straightforward, all great -- all definitely far more work for developers than testers) when, thankfully for all involved, one of the foremost iPhone devs, Craig Hockenberry of Twitteriffic fame, went and did it the way it should be done.
