...tethered to my PC? As I type this, I am on my laptop using the internet connection from my iPhone (2G)...But I cannot establish a connection to any of my instant messenger services. (ie. Yahoo IM, AIM, MSN) When using the iphone as a modem I had to configure my PC browser settings using proxy settings. I've opened up the connection settings for my messenger services but can't figure out what I need to input for it to connect. If it's even possible, please help!
