Research In Motion and Verizon have released updated software for the new BlackBerry Storm. Unlike some folks, I did not have serious problems with the original Storm release, but the new software definitely makes for much faster switching between portrait and landscape mode. It also seems to clear up some minor touchscreen calibration issues and makes for more accurate typing. All around, the Storm feels snappier after the upgrade.
The simplest way to get the new software is through an over-the-air download, which you initiate from the Options menu. Go to Advanced Options and select the last item, Wireless Upgrade. You can also download the new software through the BlackBerry Desktop on your PC.
