When I try to purchase an app for my android phone, it hangs. Apparently, you can't purchase an app without syncing. I don't want to sync anything on my phone. Is there a workaround for this? Is this just happening because I'm purchasing in the Android Market? Is there a way to purchase non-free apps outside the Android Market? Does anyone know if I can use a prepaid credit card to purchase Android apps? Does anyone have any advice for encrypting an Android smartphone? I had a Blackberry, and you can set it to encrypt everything everytime the phone is locked. Is there anyway to achieve comparable security for an Android phone?
