Ahmadferi, I think there will be no problem using the touch screen through a screen protector. I do not have my eDGe yet, but I have other touchscreen devices, all covered by screen protectors, and that has never been a problem. Also, people have reported using screen protectors on their eDGes in other threads in this forum and I have yet to read of any interference between the protector and the touch capability.

Does anyone know better??

Best of luck,
