According to the forums at dailymobile.se there's been a lot of improvement to the general interface and there's the long-awaited Kinetic scrolling along with widgetised homescreen and other improvements and bug fixes.
Al in all, I am looking forward to going home and updating my firmware tonight...nothing OTA for my handset as yet.
OK - changed my product code to NZ red, using Nemesis and then went direct to Nokia NSU to download v40.0.005
Worked a treat!
So far the differences are as follows:
Kinetic scrolling Slightly changed (more legible) font Ovi maps now supports landscape mode When entering txt, if turned landscape, qwerty keyboard is automatically activated Snappier response throughout the phone Better touchscreen response New homescreen - now has the Nokia 5530 homescreen options - if contacts is chosen, you have the contacts carousel at the top, with the shortcuts at the bottom and a there's a new music player widget which even shows album art on the home screen Lots of bug fixes
Overall it's a significant update and a long-awaited one.
I will update as I discover new things, for anyone that's interested.
