I was thinking about a GSoC 2012 project I could propose, and I came to the question of why there's no Tor iOS (iPhone / iPad / iPod touch) application distributed on the official iTunes App Store?
People have tried in the past and been rejected for being a 'proxy/circumvention tool'.
A Mac game developer friend suggested two indirect methods to use the Apple market while avoiding market rejections, that might help:
1) Use Test Flight, with Tor Project as an enterprise, using this tool to deliver to their testers. https://testflightapp.com/tos/
2) Instead of general public market, use enterprise market, with Tor Project as an enterprise, with non-employee volunteer users. Supposedly, no rejections for enterprise-private apps. http://www.wired.com/wiredenterprise/2012/03/apple-configurator/
Both solutions would probably have to have Tor Project corp to setup an enterprise where mac users would be volunteers or testers, so zero anonynimity for obtaining the software. Instead of Tor, maybe EFF or another privacy-centered group could be enterprise, esp. if it has existing membership infrastructure.
