I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
Both my wife and I droid 2 will not transfer files after the last update. I have been able to transfer files, add music, copy documents until now. So yes I do know how to connect to my PC. One just has to love how we buy these phones from Verizon and they can change the programming of them at anytime. I totally hate system updates, I have always seen some sort of problems with every phone that I have done a update on.
