iOS 6 is here and the iPhone 5 comes with a brand new hardware. It now comes with a new modem firmware (baseband) version.
iPhone 5 uses Qualcomm’s 4G LTE MDM9615 Gobi chip which delivers fast, smooth performance for a world that demands constant connectivity. Since this chip is slightly differ from the one used in iPhone 4S (MDM6610), the baseband or modem firmware is different as well. The first baseband version for iPhone 5 is 1.00.16 on iOS 6 build 10A405.
The latest iPhone now comes in three LTE versions, all of which continue to support the global GSM/UMTS services of iPhone 4S (Quad Band 2G GSM/EDGE on 850, 900, 1800, 1900 MHz, and Quad Band 3G UMTS/HSDPA/HSUPA on 850, 900, 1900, 2100 MHz) with new support for “4G” DC-HSDPA (which at up to 42Mbps is as fast as most carriers’ 4G LTE service).
Only one of the three versions continues to support CDMA.
If that was too technical for you, what this means is that if you buy an AT&T iPhone 5 or a Verizon iPhone 5, you’re pretty much locked to that carrier.
However, fear not, as we will be providing official AT&T iPhone 5 IMEI unlock. It is by far the most superior unlock solution for any AT&T iPhone (or other supported carriers) including the old 3G, 3GS, 4 and 4S.
