Hello - I have an Augen Gentouch78 and no matter what I do I cannot download applications from Marketplace. I sign in with my Google account, however, when I select Download I am told that I do not have an Android phone on my Account (which I don't). I have had this device for six months and the only thing I can do is check my Yahoo Mail account. Also, the speaker does not work - the sound is on and the volume up and still no sound. Please help!
