I've found another problem. But I don't know if it's because the installation of french user locale 3.3.5(sr3)
Now all my models except the 7912G don't have choice for the ring type. It's just became with Chirp 1. I have 7910, 7940, 7960, 7912 and 7911. So is it the french local who's mess up all my other phone?
