The sequent is getting jellybean. I saw it on the Boost website.
Update: There will be no upgrade to Jelly Bean for any of the three Boost Mobile’s phones mentioned above. Apparently, it was all a mistake noticed by Boost only when a Prepaid Phone News reader asked them about when upgrades could be expected. Boost Mobile have corrected the feature lists of ZTE Warp Sequent, LG Venice and Samsung Galaxy Rush since so now it’s clear that “The phones are not upgradable to Android 4.2.”
