I'm wondering if you have installed other (extra-devel) apps that are conflicting with yaspot in some way because my experience is very different. I have tested it a few times on my wifi and works perfectly, then I've also started using it outdoors on 3G and works perfectly for 30/60 minutes (the longest I've needed it for so far). It crashed a couple of times since I installed it but it's to be expected from any app in alpha/beta.

I agree the UI is spartan but it's perfectly usable and can hopefully be improved in the next releases, I really wanted spotify on my n900 and now i've got it!!!
