I agree but all previous iPhones had screws and they still looked good I think they r gonna keep the screws tho all the leaked 4gs had them I think and it's getting close to the announcement date
to be honest, let the screw be. i like the 2 screws on the bottom. Those 2 screw are the one keeping the phone intact. It is easy enough to open the phone but u cannot open an iphone without a screwdriver(beyond this point u better know what ur doing). since now with removeable battery, i hope in new iphone, since u can open the back u can remove simcard and replace battery without screw.
Now imagine how many people aren't buying the 3GS waiting for the 4G to come out. Usually the average consumer is oblivious to when new Apple products are coming out. They're lucky the iPad released this quarter otherwise their Q2 earnings would be done for.
