  When will my phone get the Android 2.2 update (FroYo)?  




I'm having issues to upgrade my tablet to the 2.2 system. It's a generic tablet, from Kaser, I'm using it to develop a specific application. Now the specs changed, and I need it to run on 2.2. I had a look at their website and there is no info about the upgrading. Is it possible?

If you have complete kernel sources for your device from the manufacturer, then compile your own kernel and AOSP and flash the device.. I guess this is the only approach if you don't have any alternate solutions
