In the case when the problem is triggered by a network problem, the only way for you to get out of the waiting status is to determine the cause or get the network connection back up and running first.
Another factor that can trigger the same issue to arise on your i Phone is insufficient storage or memory problems.
In other cases, the i Phone appears to be stuck on the same ‘waiting’ status after restoring or updating to the latest i OS firmware version released by Apple.
Server downtime is also another factor to consider when you encounter similar problem on your i Phone.
There are many cases where the i Phone is stuck at waiting status because the server is currently down or the App Store is slow.
Sometimes, this error can occur while attempting to install some apps or update software on your i Phone.
In some cases, this error may transpire during the i Phone restore or after performing a major software or i OS update on your device.
Although it may sound unusual for a new device to run out of storage space especially at this very early stage, there are some factors that can make this happen like buggy apps.
