My phone background is yawn-inducing. Nothing to share there, really. ♥
Some people prefer their phones minimalistic while others enjoy customizing their phones.
I have just as much fun customizing my phone as my computer, there are tons of apps, widgets and wallpapers (many are free or very cheap) and it is easy to get caught up in it once you start, then again, most people just want a phone to answer calls and send text messages and don't care what their phone looks like, nothing wrong with that either
