view story

http://forum.xda-developers.com – Hi boys, I've been using the xperia u for about a year now and i'm pretty satisfied with it's overall performance, tough i think i'm not using its hardware to the fullest.. I would like to know what your experiences with the XU are and what did you find useful (battery saving, ram cleaning, etc...)? Even ROM suggestions are welcome! I'm a pretty hardcore smartphone user, as in twitter/facebook/GPS/messaging/.. Thanks in advance, hope you guys can help me! (HowTos)
