Entel PCS has released OS 18.104.22.1684 for the BlackBerry Curve 9380. This isn't much of a step up from the last official release we saw for this device, but new is new, right? If you install be sure to swing by the forums and let us know what you find out. Things look to be good thus far, so if you're a Curve 9380 user you may want to give this one a go. As always, use caution when installing new software on your device.
