PROS
Faster processor, Siri, enhanced optics, full HD video recording, improved antenna design for speedier download speeds.
CONS
Same design to the outgoing model, gets warm in the hand after extended usage, not the most drop-friendly smartphone available.
VERDICT
Apart from the fact that the 4S has the same looks as its older brother, its improved speed will be the major benefit for those looking to upgrade. Its one of our top three smartphones at this stage, while it also sets the new benchmark for camera phones.
