I learned something today. I learned that you can only sync an iPhone with one and only one iTunes library. I downloaded a bunch of Podcasts on my PC at work and then loaded them on my iPhone. This is the first media on my iPhone. Then I came home and wanted to put some music on my phone from the iTunes library on my PC at home. The silly thing wouldn't let me drag and drop music on my iPhone. I noticed that the option to manually manage music and videos wasn't checked. Well, as soon I checked it, the sync button lit up. I clicked on the sync button and then I got a popup alerting me that my iPhone could only be synced to one library. I was faced with the option to close or to erase and sync with the library on this PC. After much debate within my head (and figuring that I didn't have much to lose, just a few podcasts) I clicked to erase and sync. Well, sure enough it took off my podcasts. I thought, this is going to be frustrating because I want to get my podcasts while at work, but my music at home. Well, a little googling and I found a fairly simple way to set up iTunes on multiple PCs so that the same iPhone can sync with them all. Here is the blog post from Andrew Grant. I downloaded a free Hex Editor HexEdit and followed the instructions and it worked the first time. When doing the find in the Hex Editor, mske sure you set your search "hex". A big thank you to Andrew Grant for his excellent help with this. Good Luck!
