PSA: Sprint's iDEN push-to-talk network rides into the sunset June 30th

The end of an era arrives Sunday, when Sprint will officially shut the door on its Nextel iDEN push-to-talk service. Subscribers who've held onto the legacy PTT standard with white knuckle grips (and extra fees) will have to switch to its CDMA-based Direct Connect offering for continued chirping capabilities -- or migrate to the likes of Ma Bell's haus. The freed up 800MHz spectrum won't remain idle; if you'll recall, it'll be re-allocated to give a major boost to Sprint's 4G CDMA voice/LTE data rollout for 2014. Hurry up and make that switch if you haven't already and relive some Sprint Nextel memories with us after the break.
