I'm not sure how I missed this last week. My guess is that I've spent too much time at work and not enough time at home obsessing about my BlackBerry. But it would appear that a CDMA version of the BlackBerry OS 4.5 for Sprint's Curve 8330 is making the rounds on the Internet. The build number of the leaked software is 22.214.171.124.
Remember, this is a leaked version of the BlackBerry OS. Install it on your production units at your own risk! If you brick your Berry, Sprint won't help you out with this one.
