Last week, the Internet connection in my building went out for what seemed like forever. Really it was only three and a half days but with my ever-escalating habit, three and a half hours can be the onset of dangerous withdrawal symptoms.
I began venturing to various coffee shops with free Wi-Fi but between fighting for a seat and their connections almost always being a disappointment next to my (usually) blazing-fast cable, I started toying with ideas of how to share my iPhoneiPhone 4's 3G connection without jailbreaking (or paying AT&T's absurdly high monthly fee for tethering).

I was a strong proponent of jaibreaking in the early days, but there have since been far fewer reasons for me to kludge my phone now that iOS has officially and more elegantly adopted most of the features of jailbreaking I was so fond of anyway.

The solution I came to was to write my own "NetShare"-like app for personal use. After poking around the web for some jumping off points (and a tip from the developer of the controversial "Handy Light" app), I stumbled on a GitHub project called "iProxy." While it does not use true "tethering" (thus the quotation marks) but rather HTTP and SOCKS proxy, it turns out that is exactly what NetShare used.
