Safe Connect uses user-agent identification to allow access. They do not have a Linux or iPhone version, so the best way to defeat them is to attempt to browse the internet using a falsified user-agent string. It takes a few tries, but usually works.
You can do one of two options:
- Download the Firefox User-Agent Switcher Addon and find an up-to-date Linux or iPhone user-agent to fake as.
- Or run a quick program I wrote: here
Either way, I have a tutorial and breakdown on how to bypass Safe Connect at that website along with links to the Firefox User-Agent Switcher if you want to go that route.

By the way, this works at my college, but I'm not sure about what restrictions they have at your school. iPhone may not work. If that is the case: use the user-agent switcher to find a Linux version that does, post it here, and I'll update the program with that string.
