Originally their main attraction and icon for the site is a frog and it's sound sound effects. However this sound effect was intended to be a sound effect for a flash file known as "insanity test".
Jamster has taken this sound and has dubbed it crazy frog sound which you can now purchase for your cell phone. With little or no changes in the voice, segments were made of a girls frog voice and other parts of the entire ring tone and sold off as their own.
While just about everything else on their site was just a graphic stolen from elsewhere, they remain keeping the frog as their spokes person for the company.
This is just the wrong way for any company to turn, it's supprising there is soo much proffit in decorating your phone. Which to people who use this site and pay for their services gladly like hold their phone as a symbol of place in society and have to be connected to every breathing mouth at all times.
Hopefully this will just be another internet business that will come and go. However so many other sites are emerging offering the same services. It just so happens jamster is whoring itself out with advertising everywhere and offering it's free music even at fast food places.
Crazy frog sound = badly made race car sound effect that was in a flash file and later pirated by jamster.
