I have to ask. Do you put any effort at all in looking for these things yourself, or just post and expect others to spoonfeed you the information? XDA is an incredible resource which can help you learn, but only if you are willing to put forth some effort of your own.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
