I think we have a pattern. After T-Mobile and Motorola suffered some bad PR from previous software updates, it looks like the company has adopted a new policy for rolling out OTA updates. Starting today, T-Mobile began testing a new software update for the CLIQ XT with a limited number of users in order to monitor feedback before a broad release.
Several carriers like Sprint often do internal testing for new software updates, but T-Mobile is the first to offer a public beta for their latest firmwares. T-Mobile is allowing 1000 users who frequent their forums the chance to download a new CLIQ XT update so they can carefully watch the feedback that comes in.
The latest CLIQ XT software is up to version 1.31.44 and the firmware remains at Android 1.5. A future upgrade to Android 2.1 is planned for Q2 2010.
