So you have got a new iPhone; you did a backup of your old iPhone and restored it to the new device. Everything seems to be working except that Apps are not installing. You try to re-sync with iTunes but nothing changes.
Looking at the Apps tab in iTunes shows that the Apps will be installed. So the question is when? Seems never right?
Well, it happened to me recently when I was doing just the same thing for an iPhone I was migrating. I even tried to restore a second time, but it didn’t matter.
I then stumbled upon the “Restrictions” settings, funny enough it was disabled. The original phone had restrictions turned on and Apps installation disabled. Just in the off chance of a bug here, I enabled restrictions, just to make sure all options are set to enabled, and turned off restrictions again.
Right after, I did another sync with iTunes, and all the Apps started to install.
There you have it, there’s a bug in the process. Maybe it was specific to my situation, where the source was an iPhone 4 with iOS6 and the target was an iPhone 4S with iOS7.
Nevertheless, here’s an experience I’ll share, in case if you encounter a similar issue.
