If there’s one thing we love when it comes to carriers, it’s cryptic emails. There’s just nothing like getting speculation swirling ahead of an announcement and what better way than to send out a hype-mailer to get people’s gears turning. Above is an email sent out today to Sprint Premier customers, giving them a bit of a heads up that something big is coming tomorrow via newsletter. Did we say ‘big’? Big just doesn’t cut it, people — this is shaping up to be a “wireless revolution”! We’re not going to make any guesses here, but considering the email references Simply Everything, Right Plan Promise and ReadyNow, odds are good it has something to do with a new type of service or plan offering. Odds are also good that it has something to do with this “Any Mobile” site listed as coming soon that was dug up by our tipster. Anyone care to wager a guess?
