Lately, I have been working on getting my iPhone ready for our long trip beginning in about a week. I started a few weeks ago by moving my contacts and calendars to the cloud with Google Sync. The next step was to move some of my music from my computer to my netbook.
I could just sync my iPhone before leaving and load it up with music but if something wrong happened (ie if I had to restore), I would lose all my music, which is why I think it is wise to move the music I want to my netbook.
There are many iPhone to PC softwares out there. My favorite is Lenogo (for Mac and PC). I use it on my everyday computer to copy music from iPhone to computer. Tansee is another solution but I like the UI of Lenogo better.
All these softwares cost money though and I didn't want to have to buy another license for my netbook so I had to go the good old way about transferring my music to my computer.
