My hubby has made it so that his former phone is now my "mini-tablet." It has no phone service but uses wifi. I'm trying to load new apps on the phone, but the android marketplace won't let me in. I can't get the facebook app from facebook either. It won't let me do anything but just browse the internet. I've never had a smart phone but I do have a gmail account; however, when I enter that gmail into the marketplace, it says it's not registered. Does that make any sense? How do I get apps for the phone?
