Review: BlackBerry Storm

you should know that the review and launch units we launched with an older software version, 4.7.0.65 at the last minute due to the discovery of a security issue in RIM's already created and smooth working OS v 4.7.0.82.

That OS is the latest and was already working with much faster and smoother performance. RIM has said a free OTA software update (presumably the secure corrected 4.7.0.82) which should fix the issue.

the Verizon Storm was set to launch with an OS higher than 4.7.0.65. The boxes handed out at the Verizon media event on Tuesday in NYC (where all those reviewers picked theirs up) actually have stickers on them that show 4.7.0.82. Yet the devices were actually loaded with the .65 OS. Did you purchase a Storm today? Take a look at the sticker on your box. If you peel it off, you'll see one beneath for 4.7.0.82. Right before the Storm was set to ship en mass, a security glitch was caught in the OS that prompted a hault of shipment. With no time to release a newer, updated OS, the Storm's that made the stores for today's launch were simply a limited number of units that were reprovisioned with an older OS, version 4.7.0.65. Yada, yada, yada.. that explains shortages and the revised December 5th availability date along with the not quite silky smooth OS. Suffice to say, you can expect an OS update to storm into town soon.
