Can I sync my iPod and iPhone to the same account?

Will anything be deleted from one or the other; can I set certain things so sync to my iPhone that I don't want to be on my iPod and vice versa?
Or you can just tell me what happens when you plug them in.aha.

Yes you can. As long as you connect the accounts together.

Yes you can have them both set on the same iTunes account- I have my iPhone, iPod and iPad all synced to the same account. To prevent deleting of your information and to put different things on each, make sure you are using manual syncing instead of automatic. With manual, you can decide what to sync and what device to put it on.

Yes and no. Nothing will be deleted, but you'll have to remember to turn off autosync just to make sure that they don't sync. Should be fine.
