In regards to this error "805a0193" occurring on February 9 2013, I'm going to go out on a limb here and say that it's a world-wide outage of the Windows Phone Store on both WP 7.X and 8.
A quick search and I've found that the error is appearing across several countries on different phones and carriers.
I guess we're just going to have to wait this one out.
That's right. In Poland too have this problem.
Sweden here. I got the same error code. Lumia 920 WP8. When they finally released Spotify, this happens...
Both for 3G and WIFI.
Edit: router and phone rebooted. All other wireless devices turned off. DNS changed numerous times. Same error.
