From the department of “get it while it’s hot” comes iTether, an app which lets you share your iPhone’s data connection with your Mac or PC. While some carriers enable this feature natively, most iPhone users will have to jailbreak their devices to tether them or pay extra for the service.
The app comes in two parts. A Windows/Mac client and the iOS app. It works by creating a virtual, software-based Ethernet port to which your computer connects via USB. That’s the theory at least — in my testing (with an iPad, not with an iPhone) the Mac app wouldn’t stay up for long enough to actually use the web. It does actually connect — after launch the app opens the Tether site in your browser — but crashes as soon as I try to navigate elsewhere.
The problem appears to be an exception with the Mac app’s kernel extension, although the iPad end seems to work just fine. Other report that it functions as described.
If you do get it working, the main problem is that you need to leave the iOS app running in the foreground to use it — no clicking around to change the music or check Instagram while you work, or sharing your unlimited connection with a friend while you do your own thing. Then again, it might just be a lifesaver that one time you really, really need to watch a Flash video out in the countryside.
If you want the app, you’d better grab it now as — like NetShare before it — iTether is likely to be pulled from the app store any time now. The developer — who also makes a Blackberry version — seems aware of this and is charging $15. The companion PC apps are free.
I can’t recommend it as the computer-side software is so bad. That said, you could download it and see if it holds up before pulling the trigger on the paid iOS app. And as ever, be careful installing Mac or PC software which requires an administrator password.
