Proxy App possible with SDK? - Mac Forums

TinyProxyをJailBreakな環境で動作はできるみたいですね。

でもNon JailBreakでやりたいという質問にはだれも反応なしwwwww

So,now there's TinyProxy for the iPhone for Jailbroken phones. I'm not planning to JB my iPhone 3G though, I really need a way to tether my Macbook to the iPhone so I can surf and such on the Macbook.

I started looking at the iPhone SDK last night and this morning. I noticed there's the "Reachability" example that attempts to connect to various sites and such through both the wifi and the cell networks and reports back the status of each. As such, it's obviously possible to control which radio system connections (I think they use the term Streams instead of Sockets?) talk over.
