Hi. Due several troubles experimented with the pk48 I had to go to pk47 version. These problems were, in my personnal case: - Not able to video playback. Even the Nokia video on startup was gone. - Not able to video recording. - Some trouble with my "fonera" wifi router N900 not seeing the wifi signal from it. - Worst battery performance than over pk47. - Issue with battery recharging when sometimes the wall charger were identified by the machinne like an usb device asking me for pc suite or usb mode. So, going back to pk47 but really thanks for the effort. I will have an eye on this. I will like to know if I was the only one with all these issues. Maybe all these things came with some personnal configurations? Even when I think I have a "standard" installation without any strange scripts doing strange things. Thanks again, guys, and keep the awesome work.
