I got new Nokia 500.
Yesterday I upgraded OS to belle in a single attempt.
Downloading nokia suite executable on my pc, installating it on my pc, start using it by connecting phone to my pc, just proceed upgrade step by step. It is damn simple. I made three visits to Nokia care and could not get it done by them. Now I feel, it was not needed. Upgradating from Anna to belle is very simpe. Now enjoying with my cute BELLE.
Though my entire exercise went smooth, I got a confusion only once with a contradictory warning message while installation. I ignored this message. Inspite of that, my belle is working fine. Please see attached image file for that confusing message.
