If you switch Apple products will you still have all your pics, song, etc?

I have an iPod touch and I have all my songs and pictures on my iTunes library on my computer. I plan on buying an iPhone. Will all my songs and pictures transfer to my iPhone from my library?

What you would have to do is make a backup of your first device, and when setting up your second one, restore it from the backup you made already and it will have all of your old music, songs, apps, etc.

Only if on the iPhone you use the same Apple ID: P

Pictures you would have to transfer yourself using iTunes, but songs, settings etc will (through the backup of course)
