Sprint offers unlimited too!

It seems like a response to the recent Helio’s $99 plan that Sprint allows its customers (in some areas) to experience the freedom of unlimited. For $119 a month you get to enjoy unlimited voice calling, text messaging, web browsing, email and picture mail, but that is only if you live in one of the following areas: San Francisco Bay Area; Upper Central CA; Philadelphia, PA; Minneapolis, MN; Tampa, FL. If you want to use a smartphone though, you will need a separate Power Vision Pack or BlackBerry data plan, which is a bit of a drawback, but still.
