Motorola's dangled an Android 2.1 upgrade in front of CLIQ XT users for what seems like forever -- now it's putting away the bait indefinitely. In a statement released this morning, the company said that despite months of rigorous testing, the phone will remain on Android 1.5. We first heard promises of an update in June last year, but Motorola quickly reneged. In November, its predecessor got an upgrade, but the CLIQ XT was left hanging. Then in December, the company announced a delay, citing "additional testing," and when those tests failed to bear fruit, it just plain gave up. Now CLIQ XT users are stuck with a phone indefinitely sporting an OS that's three steps behind the most up-to-date competition, and unfortunately, that's all she wrote -- Motorola shows no signs of pursuing another upgrade anytime soon. And that, friends, is your cue to pick up a handset made by HTC and situated on Verizon Wireless.
