No, I don't know anything.
I was just curious. The $80 plan sounds like My Way or All In. My wife and I ditched our late 2008 Everything Data 1500 in March of this year for a $50 Best Buy plan. But I'm not on Sprint any more.
Kind of funny because we ported over to T-Mobile two months ago with their $80/30 Unlimited plan and now we're grandathered!
The new unlimited plans are $95/45. The only difference is 7 more GB of tethering data. But as I rarely tether I can live with not paying an additional $15 and keeping the same tethering allowance.
If you find someone willing to give up an ED plan that's pretty much gold right now on Sprint. The only thing older than that would be the old Fair & Flexible plans with addons but those are very rare as most people jumped to the ED plans when unlimited data was launched.
