Before you send that email to The iPad Guy telling him that you’d like to have either of these apps, make certain you have enough space on your iPad.

Garageband takes up 1.5 gig, and Numbers about .5 gig.

How to check:
Settings –> General –> About

What to do if you are short on space:

• Delete pictures/videos in the Photos app – and then empty the album “Recently Deleted”
• Go ahead and do the system update that you’ve been putting off [Settings –> General –> Software Update]
• If you have a gazillion unread emails, go into Settings –>Email, and delete the account. Then set it back up [HINT: Google account]. This will NOT delete the emails, just the copies that were sitting on your iPad.
