How to distribute the mobile internet with the iPhone to other devices?

Summer is coming, and increasingly want to work not in a stuffy office or apartment, and in the country or a cozy cafe. iPhone 4 can act as an access point that gives Internet to other devices. Although the phone is easy to set up, many do not use this feature. And for good reason: because in this case does not necessarily to buy, say iPad with 3G support, - simply share the internet with iPhone on the tablet.

In the role of an access point can act only iPhone 4 with the installed firmware version iOS 4.3.1 or later. Go to Settings → Key Chain:

We turn here and 3G "Cellular Data", if earlier these features have been disabled. You will see a new item "Personal Access Point":

Here iPhone will tell you the password to the WiFi-connection:

Password simple, but it can be changed to more reliable. Creates an access point receives the name of the form "name your iPhone." Remains connected to the WiFi-compound other devices - iPads, laptops, etc.

I usually use the iPhone as a hotspot when the provider issues. In these cases, the phone acts as a backup channel.

This approach has one drawback - the phone with the included 3G discharged very quickly.
