Well at least you're honest about it, Motorola. The company just updated its Software Upgrades page, and the news isn't good for owners of the CLIQ XT, i1, Flipout, or Charm. We already knew that the first of those four phones will eternally be stuck on Android 1.5, but what may come as a bit of a surprise is that the i1 is now in a similar situation (i.e. forever doomed to Cupcake), while neither the Flipout nor the Charm will ever see an OS version more recent than Eclair.
Of course, that's not to say you can't get Froyo on these phones - in fact, there are already a number of 2.2-based ROMs for the CLIQ XT. Additionally, if you're rocking the Charm, there's a MOTOBLUR-free ROM that can be obtained from here, and Flipout owners can get their MOTOBLUR-less fix at XDA-Developers.
We'll keep you updated as more ROMs for these phones come out - in the meantime, shame on you, Motorola!
