if you have a jail-broken iphone you can do this for free. Tested and it does work.
those directions may also help with the setup of the NetShare app
I really can't believe Apple approved it in the first place. What were they thinking offering NetShare? It's on, it's off, it's on again, it's off again. Can't they make up their minds? I'm glad I bought it while it was still available. I must have been one of the last to buy it. I'll be sad when iPhone v2.0.1 disables it or they work some iTunes magic to remove it from my iPhone without my permission. Wouldn't THAT create a public uproar?
I messed around with it a little earlier today, but I couldn't get it to work.
I just checked UK & Japan iTunes Stores … can't find it.
Apple's blessing, the other doesn't … but even Apple doesn't appear to know what they're doing.
