It's now possible to set up . This feature has been available on Android devices for a while, and it's been on my own "Features I Want in iPhone" list for years. Put simply, iPhone users can now share their 3G data connections with up to five devices. This update, which arrives a month after the iPhone for Verizon hit store shelves, allows three devices to share an Internet connection via Wi-Fi and another two to go online via bluetooth or USB connections.

To use the personal hot spot feature, you'll need to buy additional data services from your cellular provider, so while iOS 4.3 supports this, you have to pay more to play. AT&T charges $45 a month for a bundle that essentially lets you use 4GB of data per month -- and it charges you $10 per gigabyte if you exceed that limit. Personal hot spot capability is a long-awaited update, but it could get costly if you use it a lot.
