Since few days ago, i had problem upgrading QuickOffice on my E71. The version offered via Free Upgrades doesn't work and i got Update Error message instead of successful installation.
I submitted a ticket to the support team few days ago and finally today i fixed my problem. The solution that was given at the first attempt didn't work for me. Today, i got another solution which works like charm. They gave me a new installer and this time, it upgrades successfully without any problem. The phone had to restart after installation, but after that, i got a new QuickOffice which has new features.
