Despite Motorola's Android 4.0 rollout schedule, not every one of the manufacturer's devices are ready for dessert -- some, the outfit says, will be put on a diet. "Obviously we want the new release to improve our devices," the company said in a recent blog post, "If we determine that can't be done, well, then we're not able to upgrade that particular device." Handsets that are bogged down by Ice Cream Sandwich simply won't get an update. Even so, Motorola affirms that it's working closely with Google to keep its hardware up to date.
