If I delete my apps on the iPad, and do not sync it with the computer, is the space instantly free? I have a mostly full iPad I want to take on a trip (not bringing computer), but at my destination I want to free up space to store photos I take on the trip (I have the adapter). If I delete all my apps and everything, does it free up the space to store my pics, or is the space not free until I sync it again? Thanks a bunch
