I went out and bought an 8GB without researching, unfortunatley. I kept putting it in and it was not reading it. So, I called Verizon and they said the 755P supports only up to a 4GB. So-out I wnet and got the 4GB card and its doing the same thing. It workds fine with my 2 GB. Any thoughts why the 4GB is not working? Thanks, TDS
