Switch between open apps: Alt + Tab
It is not bad in itself to have a lot of apps on your iPhone. Some negatives may be if many apps are open at the same time it may slow down your phone and having many apps may take up a lot of space.
no
open the app -_-
i have the same question
The iPod Touch software may be out-of-date or may be too new. iPod Touch apps have been known to not open if you do not have the minimum latest version of the 2.0 software, and certain apps will not open if you have 3.0 or 3.1 software.
The application either takes up too much space or you have too many other apps open. If there are too many other apps open, press the multitask button an touch "end all"
Open up your Library to the Apps tab then hit Check for Updates.
You do it from your IPhone app for the watch. Open that on your phone and you can change faces, add apps, remove apps, download updates.
There is no limit for how many apps you can have. That said, memory space will limit the number of apps you can have on the NDSi.
