After updating my iPhone 4 to iOS 6 a few weeks ago, iTunes isn’t able to ‘see’ it on my home WiFi network. Since I rarely have to need to sync my iPhone with iTunes, this isn’t a huge deal, but it still bothered me.

I was able to resolve this by turning off WiFi on my iOS devices, then from my MacBook, I logged into my router and delete all connected devices (on a Linksys router it’s located under: Status > Local Network > DHCP Client Table).

Once I deleted all connected devices, I re-enable WiFi on my iPhone, relaunched iTunes and boom, my iPhone was showing up once again in the lefthand sidebar.
