Samsung SPH-i500

Sure thing. Easy as can be! http://i500.nopdesign.com/ Down-load the one way messenger software here. I've been using it without a problem for 7 months or so on my I500. Works fine. There's also a Skin selector there that allows you to add new wallpapers to the phone. It tricks the phone into thinking the new wallpaper is the "Trees" default picture, but doesn't replace it. Any of them you don't think look too good, you can delete from within the software with just a click. Pretty sweet deal, and it's all free, but I suggest that donations are a good thing
