OS 5 adoption unchanged since November

For two straight months now the rate of upgrades to OS 5.0 has remained unchanged. January’s rates of OS 5 use on the devices that can be upgraded from OS 4.x are almost unchanged from November, and in a few cases even down. Given this stability it seems unlikely to expect any further change in these numbers in the future. (The overall use of OS 5 or higher has continued to increased as RIM is no longer selling devices with OS 4.6 or 4.7).
