Variations of this have probably been discussed, but I just wanted to report my experience.... I got a wifi 64gb iPad today. I decided to not get the AT&T 3G built in, even though the data deal isn't too bad. Instead, I'm using a Cradlepoint PHS 300 portable router, combined with a Virgin Broadband 2 Go USB stick. Pleased to report that it's working great with the iPad. Download speeds depend on where you are, of course...I've been testing this in a pretty bad signal area...but even in a weak area, I'm downloading comics (KICK ASS!) and streaming Netflix with only slight hiccups on either. I was a little surprised that I had no trouble setting it up for iPad....it just picks it up as a wifi signal, I have to login through the Cradlepoint site that comes up automatically (as with any device). When I set this up to use with a Mac Air and Pro, I had to install other drivers via USB, and I was worried there might be a driver problem with the iPad. Nope. Whew. Really nice to be able to use other devices on the go at the same time. I wound up buying the router and the Virgin card...which allows incremental data buys depending on what you need (prices between $20 and $60)...so I could ditch my AT&T cell card (which was a flat $60 a month, and I never wound up coming close to the 5G limit....I'm usually near a wifi signal). One warning, though. I bought the Cradlepoint router from Woot a couple of months ago. To use it with a Virgin Broadband 2 Go card, which accesses the Sprint network, you have to download the latest firmware for the Cradlepoint. When I first got the Sprint card, it wouldn't work at all with the Cradlepoint....and when I called Sprint and Virgin about it, they said NO portable router would work with the card. Not true. All you have to do is get the latest Cradlepoint firmware, and it works like a charm. The Cradlepoint router and the Virgin card are two small extra things to carry, but I emphasize small (basically a thumbdrive and a router that's smaller than, say, a DVD case), and I liked the flexibility in pricing and multiple device use enough to go this route instead of built in AT&T. Sorry if this is a dupe, I'm a latecomer here and don't know how many of you have tried this...just wanted to report my version of this workaround works just fine.
