Netshare iPhone tethering app reappears in the App Store. Update: oh, it's down again.

Well, who knows what's going on here, but Nullriver's Netshare iPhone tethering app has made a reappearance for download by direct link only in the App Store, after getting unceremoniously yanked last night. It won't show up in searches, but you can still get it if you know the link -- that's a bit odd. Nullriver told Macrumors that it doesn't believe the SOCKS proxy violates any of the App Store SDK restrictions, and that while AT&T has tethering restrictions for its 3G network, other carriers around the world don't, making the app legit in its opinion. Looks like Apple's agreed -- for now. We did a quick hands-on video last night, check it out after the break.

Update: Yeah, it's offline again. This has really got to be drumming up sales, though. Well done, Nullriver. Thanks to everyone who sent this in.
