Assuming you have Verizon,
You can just upgrade to a Pixie for free! The Palm Pixi standardly has a tethering setting. No having to download anything! Right out of the box it can be transformed into a 3G HotSpot, from the touch of a button.
Like I always say, why have a Super SmartPhone when you have an iPad, after all your phone should only need to be used for calls, right? Your iPad can do everything else! & If your like everyone else, your phone shouldn't be seeing much daylight since iPad and you have met. The Pixie is a smart phone, just not AS smart as a Droid, just my point of little view
. Oh and P.S the Palm Pre does the exact same thing. Or, if your prefer a Blackberry, it also does the same; for 49.99$ ofcourse. (one-time fee). I'm sticking to the Pixi
