We were surprised by T-Mobile bringing back the Sidekick iD last month. Just in time for Christmas, they’ve brought back another old friend, the Sidekick Slide. T-Mobile is offering the Slide again for $99, $200 off the retail price. It’s the same price as the newer Sidekick 2008, so this is probably only interesting to people who like the form factor of the Sidekick Slide. So if you’re a fan of a smaller more compact Sidekick that doesn’t have the characteristic flip, now is your chance to grab one! With these recent “returns from the dead”, it makes us wonder when we’re going to see the Sidekick 3 available again!
