Hi migueli2,
what do you mean by tones reset? If you mean that tones (or sounds) are quite silent after soft reset or actually even after turning phone off and back on, then that is normal.
Thanks all for your answers.
Actually I bought some time of my day and did a hardreset that I hate so much.
Anyways, I'm glad I did it because I was have some minor bugs/problems and all good now.
The thing with the ring tones getting reset (even the tone I choosed for mail reset) everytime phone booted its gone.
So if anyone experience this problem after GDR3 dev preview, hard reset is the solution
