The tethering, namely the ability to use your wireless phone as a modem and dirottarne the data connection directly on your computer, is a function disabled on iPhone 3G, although technically possible.

But if you are lucky holders of the device in question and you need to exploit the connection, know that there is a way to do so, provided that he daring, nerves balances, and the knowledge to be violating the contract signed (if you have subscribed any). Everything, in fact, basa jailbreak on the phone through the only means currently available: Pwnage Tool 2.0, with all the risks involved.

Nate Tru has made available on its blog a detailed guide - in English - which explains exactly how to obtain this result. While the tethering probably violates the terms of the contract with Vodafone and Tim, it is also true that virtually all other smartphones support such functionality and that many users will not want to abandon for any reason.

Of course, provided that enough to make you succeed the 600 MB per month of a typical Italian.

If you are lucky holders of a ambìto iPhone 3G or - but technically you should not, at least for now - a long-generation iPhone equipped with the new firmware 2.0, then you may have already noticed that sometimes the phone has moments of annoying slowness and hesitation. If returned in this case, consolatevi: you are not alone.

In this thread on Apple forums, in fact, read several complaints about it, all very similar:

Mainly [occurs] in contact screen, but also beating texts. When appear contacts, I click on a name even two or three times, to appear before the result, and because of the delay in my response often happens accidentally clicking on the telephone number and initiates the call.

It seems that in most cases, turn off and on both momentarily resolution, but often the problem occurs soon after. It ‘obvious that, regardless of the extent of the problem, Apple will soon come to the rescue users with a permanent solution. A good opportunity, perhaps, could be the imminent firmware 2.0.1.
