According to Engadget Mobile, Sprint will replace its BlackBerry 8830 World Edition with the BlackBerry Bold some time this quarter. While running on Sprint's CDMA network, the smartphone is said to have dual-mode functionality, so it'll work on international GSM networks to give you world-roaming capabilities.
Other reported additions include a slightly updated design, more memory, and EV-DO Rev. A support.
The Boy Genius Report also chimed in with a few more details on the Sprint Bold, which it calls the BlackBerry Niagara: a full QWERTY keyboard, 480x360 nontouch display, assisted GPS, and a 3.2-megapixel camera. As expected, there's no official confirmation from the carrier or RIM, but as always, we'll let you know as soon as we have any information.
