i recently got the LG Optimus 2x and i have been trying to figure out how to add music and video to it but havent figured it out yet. also i tried working with the calender recently but couldn't figure out how to colour code it everyone says that you should see a USB icon appear in the top section of the phone when you hook it up to the computer but nothing appears on my phone ?? are there some drivers i need to install for it because it didn't come with any ??
