Wow, you guys are awesome! I've got Barnacle Legacy installed, and it works great! No degradation in wifi performance that I can see. Looks like it uses a different approach than Wireless Tether, which makes it more compatible across different phones.
Only downside I see at the moment is that it can only use WEP encryption, which was rendered obsolete ages ago. WPA support would be a big plus. I don't necessarily have anything to hide, just don't like to make myself an easy target.
