I love txting and taking pictures using my cellular phone. More than that, I love pimping it. Making it look, feel, and sound the way I like it to be. All of that won’t be possible if not for the website sources which freely share their pimping goodness! What I have here are the stuff you’ll gonna be needing and the links where you can find them.
The stuff you need to personalize your mobile phone:
Wallpapers - these are still images
Screensavers - these are animated images
mp3 - to personalize your ringtone or message tone and for some their alarm clock tones.
Themes - a package of pictures and backgrounds having a common subject.
Games and Applications - these to extend the function of your phone.
The sites wherein you can get all of the the stuff above for free.
