The Verizon iPhone will come with Wi-Fi personal hotspot service built-in, and GSM/AT&T iPhones might get the same feature in March with iOS 4.3 -- but you can have it today on any iPhone with MyWi on Jailbreak.
MyWi is a wonderful little app and in my opinion, a major reason to jailbreak on its own. MyWi alllows you to create a wifi hotspot with your iPhone. I have a wifi only iPad and I never even considered purchasing the 3G version. I simply tether my iPad to my iPhone. Just be wary of doing this if you don’t have an unlimited data plan. As of writing this, MyWi currently costs $19.99. It may seem like a hefty price tag but you’ll pay that in data and/or tethering fees in less than 2 months. You’ll only pay for MyWi once. You do the math.
