Another year, another Imagine Cup. The annual competition, sponsored by Microsoft, gives students the opportunity to apply technology to tackle hunger, poverty, and other global problems, thereby making the world a better place (for you and for me, and the entire human race). We'd say the finalists deserve a pretty cool reward for their efforts, right? According to a status update on the Cup's Twitter account -- an update that's conspicuously been pulled -- one of the prizes for finalists is a Windows Phone with Mango pre-loaded, a jackpot they'd receive by September. We're not completely certain if this will be a pre-release version intended for developers or if it's an indication that the final iteration will be ready for public use by this time; we've only heard that Mango's slotted for a fall release, so both are definite possibilities. Since many of these students are developers, however, it's entirely possible they'll receive a prototype device with an early version of the firmware. No phone could replace the warm feelings in their heart for such a great accomplishment, but at least they can share their joy with built-in Twitter integration.
