It depends. The iPhone 4S has the same design as the CDMA (Verizon) iPhone 4. If you have a case that will only fit the GSM (AT&T) iPhone 4, then the 4S will not fit (at least, not well).

Two ways to figure out...
1. If the case only fits GSM iPhone 4, it won't fit iPhone 4S. If it's compatible with both AT&T and Verizon, it will fit 4S too.
2. Check out the mute switch (ring/silent) cutout. If it's quite large, then yes for 4S. If it's small, then refer to the 1st way...
The only difference between a AT&T iPhone 4 and 4S is the position of the mute and vol control buttons...
Some of the cases that had left the button area wide open, it should fit.
OR
If the case is designed for CDMA iphone 4 it should fit the 4S also...
