Hello all...new to this forum. Have been searching for a few hours today trying to find a fix for "Error -2048: Couldn't open the file filename.3gp because it is not a file the QuickTime understand." problem when the file is copied from the Verizon Motorola iphone to the computer. On the iphone the error smiply reads: "Error: File cannot be displayed or played" The file is 44.1MB in size so I know something is there. Please...someone have good news on how to fix this problem.
