Apps won't update: "not enough space"
My sister has a 3rd generation iPod touch. Every time she tries to update an app she gets the message "there is not enough space to download [app]. Please delete some photos or videos." it's an 8 gig but has 6.8 capacity with 0 bytes availabe. She has 788 songs, 0 videos, 71 photos, and 22 apps. She has deleted a significant amount of photos and apps but is still getting the error message. I have 5 pages of apps and aml able to update. Is anyone else having this problem or knows how to fix it? Btw her ios is 4.2.1.
macbook, Mac OS X (10.5.8)
