I have a Movistar dual SIM in my Spanish Movistar Pre. This especial an unique SIM from Movistar has two cell numbers (business and personal) with their respective PINs to access each number. In Treo 650, Movistar build an application that switch between the two numbers. Talking with Palm Support have no result: that dual SIM are unsupported. Talking with Movistar: they build the application to WebOS to switch. In a future. May be.
Actually, I need to restart, waiting two minutes, to switch between my numbers.
I try some patches related to network but nothing work.
Any help.
Thanks in advance.
