Will iPhone 4s be cheaper?

It is natural. Whenever there is a new app on the market, the existing apps will always be cheaper so as to attract customers.
Compared with iPhone 5, I still want to get an iPhone 4S, I think it is OK enough for me.::alien::
I think it's good they have both iPhone 5 and iPhone 4S as options, and not just 5.
I'm more than happy with my iPhone 4S hand-me-down model. And even my sister just got herself a new iPhone - 4S as 5 was out of stock, and it still does more than everything she needs for quite a while. :) and of course being cheaper than when they only had 4S does not hurt. I think she actually even likes the 4S form factor more than 5.
