> Apple's ToS for Apps:

> A "Deepful" analysis of GPL vs Apple's ToS:
> http://mailman.videolan.org/pipermail/vlc-devel/2010-November/077486.html
> To make things short, Under ToS, Free App is only for personal  
> noncommercial use and you can only share it on five iTunes  
> authorized computers.
> Under GPLv2, once you have been granted license rights, you may not  
> impose further restrictions on the recipient's license rights.
> Since Apple ToS is restricting you to use a GPL software just to  
> personal noncomercial use, there's a conflict. Since you can only  
> share it to your five iTunes authorized devices, there's a conflict.
> One of the most noticed cases was the VLC Media Player:

> Workarounds:
> 1. Since the blend files are outputs from the program, they're not  
> covered under GPL Terms. You might write a "GPL free" app ( what an  
> insanity!!!)  to manipulate the Blend file and license it according  
> Apple's ToS.
> 2. Like Tony said, Change your tablet for something else that truly  
> support GPL apps. Android is the first option, not to mention HP  
> WebOS or some old fashioned Windows/Linux Tablet.
> Hope this might help!
