Good to know. Will be useful at least for notifications. I can have skype runing on my phone then.Not any more. It uses Skype for Web now.There's a pidgin plugin for skype, but only for basic IM, no file transfer, picture share, voice, or video.
That requires Skype to be running though...
I tried Marble, it is decent but as far as I found it has no elevation/3D and no precise satelite imagery.
