This tip is working for all idevices under ios6. Won't work with ios 5 because it needs Passbook to work.
Open Safari and go to cydiahacks.com/
Press on Get PassHack
Tap the button above: 😄 (Add to Passbook)
You should see this...
Tap on the i in the bottom right corner.
You'll see this...then tap on the link of the app that you want the icon hided...(I bet you'll choose Newsstand !)
Yes I'm French...for you it will be written in English...So click Install
Back on the springboard, you'll see a popup saying that the app couldn't be download...Tap finish
Now delete "Newsstand Hide" or the app you wanted to delete the icon...
Tap Delete, and Voila ! It´s done !
To make any deleted icon come back, simply reboot your phone...And to delete an icon again, go to Passbook...Passhack is saved and you'll be able to hide it again easily. Please Like and Comment !
