This is the iPhone 4S introduced by Tim Cook at Apple's 'Let's talk iPhone' event on October 4th 2011. It is very similar to the iPhone 4 (CDMA model). Compared to the iPhone 4 (CDMA model), the iPhone 4S contains an updated GOBI GSM/CDMA chip, a SIM slot, and a similar (but redesigned) antenna. The name used in firmware is iPhone4,1. On 10, September 2013, Apple started to sell only an 8GB, listed as 4s, which had just released.
The iPhone 4S has hardware support for both GPS and GLONASS signals for location determination included with the Qualcomm MDM6610. Apple's online advertising material for the 4S mentions GLONASS support, but as of October 20, 2011, no further details about this support have been publicly revealed.
