I have a QMobile A100 with Android 2.2.1 (which is very old). I want to upgrade it to the new version (2.3 Gingerbread). In
Settings > About phone it shows that there are no updates to the firmware.
How should I update my device? It is not a popular phone and I cannot find an updated ROM for it.
If it matters, the phone has a 500 MHz CPU, 200 MB RAM with 250 MB ROM.
