Should rumors hold true, July could be the month of the BlackBerry. Aaron reported on the BlackBerry 8520 earlier in the week, and since then, documents have leaked from the Walmart corporate structure lending credence to a July release date. Upon launch, the date is said to have a price of $78.88, with a drop to $48.88 in October.
To recap, the Curve 8520 is the first BlackBerry to offer an optical trackball, and will potentially launch with OS 5.0. The interesting detail is what it's slated to replace: the BlackBerry Curve 8320, meaning that the 8520 is in fact going to be the new "Curve" device.
