Does anyone have the new phones with the sim card in them and have problems?I have two seperate phones, one verizon and one Cingular. I have the new GPs technology , but was talked into two new units because of the new sim cards. Since i got these i have nothing but problems. I never did have a problem with the older models. Thinking of going back to the older model. Does anyone know if all the new models will have the sims card? Thanks
