Considering it's incompatible with SemiTether, I won't be trying it. I just don't see my getting access to Siri anytime before I can upgrade my phone in a couple of months - at least until I can afford to spend $200 on a new phone after then.
 
I don't think it's so much useful, you need to be in your wifi. What's the point of having Siri if you can't (you can if you're skilled with those VPN stuff) leave your home.
 
my contract is up Jan 8th some will rather upgrade to the 4s or wait for the I5. However this just isn't worth the hassle to me.
