Why does the Android Market site show these errors?
Many friends of mine from the same country (India) have been able to download and install the apps from the site, some with the same handset.
download apk files from other sites, and install via computer
Have you tried using a proxy?
Select "Advanced Options" and chose a USA server.
Yeah tried it . But when I login it ( Google ) shows an error "Your browser's cookie functionality is turned off. Please turn it on. " .. I have dont that .. But still , it doesnt work :(
Can you clear your data in the market app and try another proxy or install a VPN. Do you have to install the app from Google?
