Answer Can not download Apps On iPhone_banyak people complain of problems iDevice fail to download applications from the App Store. Sometimes fail to perform the update,

After studying the issue, the similarities between the complaint and the others that we found were these problems arise when a new iDevice updated/upgraded to the latest version of iOS (usually via OTA).One possible cause of this problem is the misconfigured on your iDevice after iOS update process so that the App Store can not serve your request. Another cause is the presence of one or more application download process is suspended (pending) that may occur due to a sudden halt due to network problems or due to discontinued / pause by yourself.
Unfortunately, this problem is quite common, and so far no special way that is guaranteed to work 100%, other than to follow a few tricks/workaround, or download the application via iTunes and sync later.

Although I can not guarantee it can work perfectly and solve your problems, but the following are a few tricks you can try:

Reboot your iDevice. Probably only need one, may also need to be two to three times. Keep trying.
Make sure you're connected to a Wi-Fi network or a mobile network that is stable enough to download an application. You may need to switch between these two types of connections to determine which are the most stable.
If you feel the Wi-Fi connection at your place of troubled or your mobile operator's network is unreliable, try to use other Wi-Fi network or another SIM card.
Disable Restrictions (Restriction). Go to Settings> General and turn off Restrictions. If indeed these features are needed, make sure you allow (Allow) "Installing Apps" that you still can install applications from the App Store.
Disable Automatic App Updates (update applications automatically). Go to Settings> iTunes & App Store, and switch off the "Apps" and "Updates" from the list. Its function is to prevent the application and updates are downloaded automatically or without your awareness. Useful if you are not always located in areas with a stable internet connection / toned.
Sign out of the App Store. Go to Settings> Store, then tap the Apple ID and select the sign-out. After signing out, reboot your iDevice and sign back in with your Apple ID and try to download an application. Remember yes, while entering the password/sign this, do not let one.
If it still fails, try to Reset Network Settings, accessible from the Settings> General> Reset. But remember, the network reset will erase all existing network configurations previously on your iDevice, including wi-fi password and APN.
If it still does not work well, try to restore your iDevice from iTunes again. After the restore process is complete, you may need to adjust your iDevice as a new device (set as new) for all configurations in which they innate or standards. Then try to download an application from the App Store. If successful, continue to do poses restore from backup to restore the data that you have a previous backup.
The additional trick is to delete a file, or files downloaded applications fall and accumulate on an iOS directory.

Here's how you can try:
Download and install the file manager application to your computer that can be used to read the file system iOS. Can explorer, iTools, i-Funbox, etc. up to you.
After you install one of them, run the program.
Connect your iDevice to the computer, and wait until your iDevice has been detected properly, and appears in the program window.
iDevice If you've read properly, search the Downloads directory (located in / var/mobile / Media / Downloads).
If my guess is correct (buildup), then you will see there are several folders with names in the form of random numbers that contain the files of the application you want to download from the App Store.
Scroll to the bottom, and you will find a file SQLite DB, for example, downloads.10.sqlitedb. You do not need to delete this file but simply change the name alone, for example, download.10.sqlitedb_old.
After changing its name, close the program, unplug your iDevice from the computer and reboot your iDevice.
By following the above methods may be completed your problems, and your iDevice back to normal
