I'm assuming this plan will be usable on any Boost Mobile or Nextel iDEN phone. Not that it gives you a wide brand selection, but I have heard rumors about an iDEN messaging phone. Retro? A bit...web speeds will likely not venture above 20 kbps in most areas. But if you want unlimited everything on a nationwide network...one that's probably a lot better than, say, T-Mobile's...this is it. Just realize that if you go iDEN your phone standby battery life will be about three days, real-world battery life closer to one-and-a-half, and said phone will be on the large side compared with CDMA and GSM models.
Sppeaking of CDMA, it sounds like Boost Mobile will be phasing out their area-limited CDMA plans, which you couldn't get in some areas (I'm thinking due to varying levels of network load across the country). I'm personally a little sad to see them go...you could get a Motorola KRZR (decent phone) on an unlimited talktext/web plan with Sprint's network and EvDO data. But Boost Mobile started as iDEN, and by pushing the dimmer switch on CDMA unlimited plans they're getting back to their roots.
Also, Virgin Mobile, also on Sprint's (entire, no "travel charges") CDMA network, has a few decent phones (the Audiovox...uh...UTSTarCom...uh...PCD Shuttle, which has EvDO) and they hae unlimited talk and messaging, and nearly-unlimited-for-a-non-smartphone (50 MB) data plans. It's just more expensive to go CDMA than iDEN... $100 for Talk + Messaging + Web, $50 fo 200 anytime + 500 nights/weekends + Messaging + Web.
But I digress...the point is that, if you can stand using iDEN, and want unlimited service that's reasonably close to nationwide, Boost Mobile's new plan, coming in a week, fits the bill.
