I have done upgrade through Faster Application Manager..But, I do not see much improvements..(or I would say that I failed to notice that some bugs are fixed and performance improved.)..So far noticed that whenever I receive call, my call UI does not flicker..also I felt browsing OVI catalogue is much faster..(but that depends on internet speed? Earlier at same speed..OVI store was bit slower..) What is the best way to know that you are really running 1.3..I checked from settings->about product..I see that version is 20.2010.36.2 . But, does that really mean PR 1.3 is successfully installed? Why these questions..because FAPMAN did not ask me to reboot...I have done that manually and saw not much difference in using..So what I am missing to notice in PR1.3
