Here is the list of wap sites I found while browsing:
This site contains huge database of Bollywood polytones, wallpapers, Animations, Games…etc.
I wonder how he (Gautam) maintains this.
Lots of downloads, Online Image Software Nicasso allows you to make your own wallpapers, Operator logos, GIFs etc. It also provides a service called gmail-mobile. This is not official gmail, but it works almost anywhere in world on any GPRS enabled handset.
This too has good collection of bollywood tones, classic as well as new like Dhoom2, wallpapers, animations etc..
