hi, im using a vodaphone south africa unit in the philippines as it was suppossed to be unlocked and working anyway, please help me.. I cannot use the phone if I will set the network to 3G and 2G. The phone will reboot if i use that settings. Right now, the phone worked because i set it to 2G only.. it is very slow, i know that this model will run 3G.. I hope you can assist me.
