I try to use the market app but I keep getting kicked back out half a second later. The gmail app does the same, so I presume the two problems are linked. I have no other problems and gmail works fine when not used via the app. This thing is seriously pissing me off! In settings, I tried to clear the data and cache from the market app, but the data reappears later. I have a nexus s on 3, with the recent ICS 4.0.3 update. Any advice would be gratefully received!
