More people losing their jobs means more people with free time to build an iPhone app while they look for a new new job. Plus, a poor economy lowers the market for these unnecessary goods. So it is likely the result of a serious recession is more competition for fewer customers. Apple could reduce the number of iPhone developers by charging more for the SDK, or by charging a larger transaction fee. I wouldn't be surprised if Apple did increase the costs substantially sometime soon. In particular, I wouldn't be surprised to see the standard transaction fee increase substantially, with tiered percentages based on price and/or volume (e.g. start $1 flat transaction fee + 30% of the price for the first 1,000 copies, then reduce the percentage gradually for each 10^nth copy).
