Upgrading your Android device? Read this first

Last month, we wrote an article about what to do when upgrading your iPhone. Since then, we've received several requests to do a similar post about Android devices. Providing uniform and easy to follow instructions is a bit harder to do for Android, because there are many differences between make...
