I am using Sony Xperia X10 from last few months and it is really serving me the best. I am happy that I own this mobile. Now the thing here is that I am having the Android 1.6 operating system on it and I have decided to upgrade the same. Actually I have tried to upgrade it for two times but on I have failed on both the occasion. I don’t know what is happening with it and why I am not able to upgrade my system. So please help me in this case and then just let me know how to upgrade the same.
