I have this second hand tablet made by Wondermedia. Basic, but it seems to work well. It has the previous user's email which I can't remove because it says it is associated with some applications, so I want to take it back to factory default, but I don't want to lose or lose track of some of the good things he seems to have installed. (For some reason the search in Android Market doesn't work). Is there a simple procedure to back up everything and later reload just any apps that I want? The book doesn't mention backup. Alternatively, can I get Android Market to display alphabetically instead of just random lists of names? As you can tell, I'm a beginner.
