Dual Sim Card with the Pulse

[Guest philipsp]

Hi

I was wondering if anyone had tried a dual sim card adaptor with the T-Mobile Pulse. I would like to use two Sim cards in the phone and was wondering if anyone had tried using something like Dual Sim Adaptor. I was also wondering if it was possible to use a T-mobile Sim and a Orange Sim in the adaptor without unlocking the phone.

Thanks

Philip
