Nullriver’s NetShare Tethering for the iPhone: It’s Baaaaaaack!

...and it works--at least kinda-sorta. But it's not the miracle I'd hoped for.

Curiouser and curiouser. Yesterday, a $10 iPhone utility from Nullriver called NetShare showed up in Apple’s App Store. It promised to let you share your iPhone’s wireless data service with a computer via the computer’s Wi-Fi connection, giving you the potential to get online in places where you can’t find a hotspot. Shortly after it appeared in the App Store, it disappeared; that was less surprising than the fact it was there in the first place, since AT&T offers no official sanction for using your iPhone as a modem.

Today? NetShare is back in the App Store. I’ve seen no official word from Apple, AT&T, or Nullriver about what’s going on here, and whether using NetShare is okay, not okay, or in some fuzzy area in between. I’ve pined for the ability to tether my notebook to my phone’s modem ever since I dumped my AT&T Tilt phone for an iPhone 3G, though, so I downloaded, configured, and tried NetShare as fast as I could.

I’ve given it only a quick try so far, not an extensive trial. For a few minutes I was up and running, using Safari to surf the Web (including YouTube) at decent speed and chatting on iChat. That was a kick. But other than that, NetShare has been kind of a pain–it’s safe to say it’s not the seamless iPhone tethering solution I’ve been looking for and would happily pay for.

NetShare works by setting up a peer-to-peer Wi-Fi network between your Mac (Windows support is promised soon) and the iPhone, then using proxy access to let your Mac piggyback on the iPhone’s internet connection. This requires some futzing around with network settings on both the iPhone and the Mac; Nullriver provides instructions, but they’re confusing in some places and simply wrong in others, and they’re far from complete. They also don’t mention the fact that they only get you as far as making Safari and iChat work; I had to reconfigure Flock to use NetShare’s proxy myself.

(Side note: A forum member over at MacRumors has provided instructions for using NetShare that are much better than Nullriver’s.)

Every time my iPhone went into sleep mode, my network connection died. I reconnected only by randomly fiddling with network settings and never figured out what I did that would get the connection working again. And when I was done testing and wanted to get back on my Wi-Fi network, I had to undo some of the settings that NetShare required me to change.

In short, if you’re a geek with a need for a way to connect a Mac via iPhone for emergency use, NetShare might fit the bill. But I found it way too much of a hassle to contemplate using it very often, even if AT&T were to give NetShare its blessings.

The good news: NetShare proves that there’s no technical reason why an iPhone can’t double as a modem, and the fact that it’s on the App Store would seem to suggest that it’s not unthinkable that a more polished tethering application along the lines of June Fabrics’ PdaNet couldn’t be approved by Apple and at least grudgingly accepted by AT&T.

But I say it again: If a future upgrade to the iPhone OS had some sort of official “Tether to Computer” option, as my Tilt did, I’d cheerfully fork over money to AT&T.

And I’d love to learn exactly what the deal is with NetShare’s appearance, disappearance, and reappearance, and whether Apple is really selling a piece of software that AT&T doesn’t want you to run…

    I got a bad taste in my mouth for apple products trying to migrate from commodore programming to apple II programming many years ago…It is good to see apple has made a strong move in the posix direction and I’m starting to consider their products…but I’m not an owner of an iphone or any other apple product. However, if the iphone came standard with netshare capabilities on a national network with an unlimited data plan, I would be proud to join back up with the apple family. But it looks like apple is up to its same ole same ole games, living in AT&T’s hip pocket instead of in the customer’s pocket. Will apple ever be customer centric? Don’t count on it. They’re just moving from being adobe’s whipping boy to at&t’s whipping boy, and we all know at&t is nobody’s friend. In the mean time, you can grab yourself a prepaid phone for $30 from a company like boostmobile and have unlimited (albeit nextel=slower than the at&t network) data for about $10 a month that you can use on phone with Opera-mini or tether (with only a $5 cord off ebay and no software needed) to your laptop, linux or symbian pda, or windows subnotebook, all of which cost the same or less than an iphone. Exactly why should anyone want an iPhone? it’s not for the apple customer service (Blocking useful apps from you? how nice) and its not for at&t service (surcharges anyone? hidden internet fees? passing on the blame for hidden fees from third party at&t contracted providers and billing you anyways? signing you up for two year contract extensions you didn’t ask for? transferring you back and for from one service to another with contract extensions and reduced services, while claiming its a corporate thing? the joys of at&t/cingular/at&t customer service)
