Is the Virgin Mobile truly unlimited?

It is truly unlimited. you would need something like the MiFi though...

Any MiFi device broadcasts a WiFi signal, (802.11 B/G/N), which can be picked up by any WiFi enabled device, such as iPad, iPod touch, or iPhone. (or any laptop as well, for that matter)

Do you have a particular mifi device that you can recommend? And what about Virgin mobile coverage? ( I guess I could Google this, but, since your here.)

Mifi device? I have been reading about them, but there are good ones and bad one just like anything else.

It would probably have to be one purchased from Virgin (or Sprint) as most phones in the U.S. (and the MiFi is just a highly specialized cell phone) are what is called "subsidy locked" which means they will only work on one carrier's network. So, a MiFi bought from Verizon Wireless, even though it's CDMA, would not work on Sprint's network. And AT&T and T-Mobile use GSM so nothing they sell will work on a CDMA network.

Or Verizon comes onto the scene...

I have had the Virgin mifi for a while now and it seems to me they limit it in real life by the slow connection. Yes, you can use it as much as you want, but it frequently operates only at 802.11b speeds, making it completely useless for anything involving video, which effectively chokes the amount of bandwidth you can use.

It's fine for something like traveling where you just need access in the car for maps and looking up quick info, and are expecting to have reasonably fast wifi at your destination, but you're not going to spend an evening watching streaming movies on this thing. I also doubt I could easily upload 35MB files to my idisk.

Unlike a brody I have never had to use firefox, but the darn thing does tend to forget it's been set up rather frequently, so if you get one, take your setup info along with you or you could get stuck.

To anyone considering purchasing one, I would say that in addition to the glowing review that was in the NY times a few weeks ago, you should read the comments in the followup post there. I don't think he really used it enough.

Well, on the plus side, you don't have to keep paying if you don't use it, so it's just the upfront cost (not that that isn't plenty). Personally, I wish they offered the 100MB for a month rather than 10 days, since for quick email checking that would be just about right.

I find that the connection often goes zippity-doo early in the morning, then slows drastically as the day goes on.
