I'm looking to buy a software that lets you to create your own ringtone. If this a good software? It is compatible with Samsung Slash M310?
Yes, Ringtone Creator is a good software and it is able to create ringtones compatible with your device. Unfortunately, it has been discontinued by Unwiredtec and you cannot purchase it anymore. I suggest you to try Free Ringtone Maker, All Free Ringtone Maker, or AudioGizmo Ringtone Creator. All of them are free of charge, easy to use and can create ringtones for your Samsung Slash M310. If you're not satisfied with these tools, you can try Xilisoft Ringtone Maker. It is a most complex utility that will cost you around 19.95 dollars.
