Cellphone Wallpapers and Ring Tones

I got a new phone yesterday and I would to get a new wallpaper and ring tone for my phone. The phone's sound settings has crap wallpapers and even crappier ring tones unfortunately unlike my previous phone. :cry:

So, do you guys know any good sites where I can upload a wallpaper to fit the Samsung Intensity model. I would also like to find a place where a can download a short ring tone (mp3) snippet of Aphex Twin's Alberto Balsalm.

As a general rule of cellphones I actually download or open the built in wallpapers to see the resolution that is needed. Thankfully my phone allows any resolution image and resizes it, but if not, you can resize your own wallpapers and put it back on the phone.
