Trouble updating ipod touch apps
I had to 'guess' at which app got stuck, based on the ones that were loaded and the one that was missing.
I had about 11 apps with 'waiting' status after I pressed the 'Update' apps button.
Somehow the app update process got stuck until the next day.
Take your i Phone/i Pod over to their home, log into their network, and see if you can get the download to resume.
If this doesn't work immediately, also try rebooting your i Phone while at their home, and see if that restarts the process.
The updated apps automatically replace the previous versions of the apps.
