I really like the organization of the menu, along with the home page being able to go from plain and blank to either favorite menu destinations(like games and at&t music) or to favorite contacts (with 3 sub-menus for extra organization).
THE THING THAT IS SEVERELY ANNOYING:

LG made it so that with the
Xenon, the user can NOT set any non-carrier tones as a ringtone. You can download a free ringtone, you just can't set it to any tone area on your phone. Not as a ringtone, message tone, or alert tone. This is extremely annoyng to me because all I want is the Battle Theme from Final Fantasy VII, which AT&T obviously does not have (I checked).
Keep in mind, the phone does supply a Recorder and a Make UR Tones app. I'm still confused... if you can't set music you record or tones from non-carrier websites as ringtones, why would they supply these options?

This one bad thing, for me, is overshadowing the good of the phone. And this is coming from someone who ALWAYS pays for ringtones unless AT&T doesn't have it. (so it's obviously not the money that's pissing me off)
