A recent study carried out by the advertising group Medialets, rvl thatin the space of 6 days, the firmware 3.1.3, which is a minor update, was adopted by almost 14% iPhone users.
As of February 6, 72.3% of users were still running firmware 3.1.2 compared to 0.8% for firmware 3.1.1 and 4.8% for firmware 3.1.0.
The firmware 3.1.3 will really take off from the moment when (reliable) jailbreak and unlocking methods will appear.
We discuss it on the forum.
