iPhone 3G as Bluetooth-Modem?

Can I use the new iPhone 3G as Bluetooth-Modem for my MacBook Pro to go the Internet over UMTS?

At this Time I use a SonyEricsson for this job. But now the iPhone got UMTS...

Thanks for Answer.

Without being able to work as a Blue-Tooth modem, I cannot see how it can be an Enterprise phone?

I currently use a Nokia N73 as a modem, and so do all of my colleagues, when we travel. This works fine - and we do pay pr. MB (especially when abroad - ouch...), and this is what we expect when travelling.

Mac OS X has excellent support for phones as bluetooth modems. And I need this before I can replace my old trusty N73.

I live in Europe and do not care about AT&T. But if the AT&T issue is really what influences Apple not to provide this functionality, AT&T should use the opportunity to earn some extra bucks when load exceeds a given "max" (that is, skip unlimited), instead of limiting the functionality of the device.

The original iPhone does not do tethering (aka. DUN). While some people ascribe this to AT&T, the reality is that the iPhone (original) does not have the required Bluetooth profile, in other words it is Apple that blocked it.

Now, what has not been mentioned here explicitly, is that if it had been possible the user experience would have been way below what Steve Jobs would consider acceptable.

I have used a mobile phone with a similar 2G data connection 'tethered' to a Mac, and the speed was truly awful. Remember not only would you be using a very slow data connection but on top of that you would have the Bluetooth overhead making the latency and speed even worse. After all one of the biggest complaints about the original iPhone is the speed of its data connection, how would it be any more acceptable via Bluetooth to a laptop?

Now, that the new iPhone is 3G, the picture changes somewhat. While basic 3G is better than GPRS or EDGE, again having used it in the real world (via a data card) I can tell you that 3G is only barely acceptable. This is why the networks have since moved on to HSDPA which is much, much faster than basic 3G, and HSUPA which ups the speed even more!

The new iPhone does support HSDPA (as well as the basic 3G data) but does not support HSUPA. So from a data speed point of view the iPhone is now up to providing a sufficiently good user experience if Apple allow it.

There has been one article by 9to5mac quoting an unnofficial O2 source in the UK, that suggests tethering will be allowed. As others have mentioned, this is possible and allowed by other phones and the same networks. I have one user in my company that has a Nokia N95 which also supports HSDPA and he has an 'unlimited' data allowance and is able to tether it to his PowerBook (he uses a USB cable but Bluetooth would be possible as well).

Personally, I am more doubtful that Apple will allow this, but I ascribe this more to forgetting to consider the changed circumstances than deliberately doing so.

Currently the Bluetooth support of the iPhone is truly dire. You cannot use a Bluetooth keyboard, you cannot print to a Bluetooth photo printer, you cannot connect a Bluetooth GPS device (obviously this is less of an issue for the new iPhone), no stereo headset support, and you cannot even connect it to a Mac at all! It would also be nice to be able to 'transmit' your 'business card' from the iPhone to another phone (of any make).

I'm sorry, but that is just a ridiculous argument. I too have used 2G tethering over Bluetooth, and yes, it's terribly slow. But it still works! The point of tethering is not to get blazing fast speeds but to be able get on the Internet no matter where you are. Sure, the bandwidth isn't much better than dial-up, but you get it everywhere: at a hotel, on the bus, in the airport, at a park... Anywhere you go, you've always got Internet access. To deny users such an important ability simply because they might not be happy with the speed is just crazy.

If you need to use the cellular network on a laptop, AT&T will gladly sell you a card devoted for that purpose. Thats how a lot of enterprise users do it. Nobody in our company uses tethering at all, they use a network card to get dedicated speed. If they need it that badly, they can afford the costs associated with it. Any other surfing can be done on the iPhone itself.

What about enterprise users who have a MacBook or MacBook Air? (Only the MacBook Pro has a card slot.) Bluetooth tethering is an attractive option in that case. And even when a slot is available, it's nice not having to pack extra equipment when traveling.

As for the cost involved, I don't see why Internet access on the road has to be a luxury that only enterprise users can afford. The card option can be the high-end, high-speed option for business people who need it, while the Bluetooth tethering option can be the low-end, low-speed solution for the rest of us.

@John Lockwood re "The new iPhone does support HSDPA (as well as the basic 3G data) but does not support HSUPA."

That's a very useful fact to know, thanks. Is this an Apple restriction? What is the iPhone's maximum upload speed in this case? O2's 3G mobile broadband supports HSUPA although the most i've seen is around 600kbps of the 2.1Mbps. I wonder if the upload limitation is also a reason why iChat didn't make it to the iPhone. MobileMe would certainly benefit from better upload.

I have another thread on the same subject going and I think this is possible and I am trying to find out why it is not an option yet. AT&T does offer plans for tethering the BB and other phones in addition to the normal data plan for the phone. Check out the AT&T web site for the Blackberry data plan and you will see that for $60.00 a month you can have data on the BB and also tether the BB to your PC. With the iPhone to get to the same place you would have to buy an Aircard and that puts the monthly fees up to $90.00 a month for two data plans. I don't use enough air time to make the Aircard worth while but to be able to tether the iPhone for an emergency or while out of town would be great and wold be fast enough for no more than I use it.

None of them have MacBooks or the air, however there are ones that use USB connections. However most enterprise users are PC users anyway.

The individual costs from AT&T for a data card is 60 bucks. The cheapest tethering plan is a 60 dollar add on with a talk plan else its 65 bucks. I fail to see where the luxury is here. Both have the same data restrictions too.

Oh and by the way. AT&T has a [USB data connect card|http://www.wireless.att.com/cell-phone-service/cell-phone-details/?device= AT%26T USBConnect881&q_sku=sku1120017] too. Its Mac Compatible.

You're on the right track. Hopefully Apple and AT&T will step up and recognize this is a legitimate need, and offer a fair pricing plan that will allow us to use the iPhone as a modem (also known as tethering), so we don't have to carry around (and pay for) two devices and two data plans. As you correctly point out, other devices clearly have this capability.

Keep in mind that your iPhone ALSO as a WiFi network interface, so don't limit your thinking to just Bluetooth. It is NOT necessarily the answer here. Google "iphone tinyproxy" to understand more.

I'm cautiously optimistic that Apple and AT&T will get it together and make sharing/tethering an officially supported offering on the iPhone too, with an appropriately priced data plan to go along with it, just like it does with other devices.

There is another similarly themed discussion on the boards

I guess we are all hoping for the best.
