Use iPhone 4 SIM in iPhone 4S?
If I use an iPhone 4 SIM in the iPhone 4S, will I miss out on hspa+ speeds? Or can "old" 3G SIMs operate at that speed no problem?

Thanks.

I think your SIM just has your account info and doesn't set what speed your phone can operate at. That's determined by the phone hardware and the data plan you select.
