Sprint subsidiary
Boost Mobile's claim to fame is its push-to-talk network, and it's still turning the other cheek on its parent's newly-minted
QChat PTT in favor of good, old-fashioned, dead reliable
iDEN. The rough and tumble i335 -- which actually went on sale through Sprint
some time ago -- is now available through Boost for $59.99 on prepaid service, offering mil-spec dust, shock, and splash resistance that should pretty much keep this thing operating for as long as the iDEN network does. Grab it now anywhere Boost is sold, if you're so inclined.
