I have a Desire S on O2 UK, I was completely stock with S-ON and no root. I installed most recent update to 1.47 and this FUBAR'd the phone (kept dropping off mobile network and not reconnecting automatically) so I used the method from this thread '[UPDATED]how to root 188.8.131.52 hboot 002 (and possibly others)' to flash it back to 'RUU_Saga_O2_UK_184.108.40.206_Radio_20.28b.30.0805U_3 8 .03.02.14_M_release'.
I then carried on and used AlphaRevX to S-Off, flashed the Ext4 recovery image and used Gingerbreak to root.
Now when I press and hold 1 on the phone dialler instead of calling my voicemail it calls a fixed speed dial number that I can't change, bizzarely it is assigned to 123 and titled Buzon Movistar!! Key 5 is assigned to 112/Emergencias and key 6 1004/Atencion Cliente.
Does anyone know where these are coming from or how I change it back to the proper numbers?
