I can't speak for your iPhone or the wifi software version on it, but the problem is kind of tough --- your phone would want to generally avoid hopping around different networks if it can get a decent connection from one, and it's not so clear-cut when you make that decision to check for other networks. (I agree you make it seem pretty clear though, either it is silly or there are more details to be learned...)
