Does PAN really works for you?
On my 770 it starts normally, can contact the news-server, but when the server starts to get the newsgroup list, PAN will lock up and finally reboot the device.
This behaviour i can reproduce.
A shame is, that i bought the 770 as is read "newsreader" on the package. Hu, maybe i am to old-fashioned, that i understand a newsgroup-reader under "newsreader" and not a rss-reader
