You cannot use a USB cable to transfer data files, I.E. files that are not music, video or pictures. I want to put PDF files on there, the phone comes with Word... yet you cannot put a word document on it. I either have to upload them somwhere and then download them back to my phone or e-mail it to myself. This can't be true... can it?! I'm too used to Android, being able to just drag and drop anything to the device.
