A few people who’ve applied the recent Windows Mobile 6.1 upgrade to their BlackJack II are noticing the network settings on the phone are disabled after the upgrade. While you used to be able to change these items (especially important to those with unlocked devices), the carriers apparently convinced Microsoft to lock them so less experienced users would stop messing up their phone with erroneous settings. Mike Temporale at Mobile Jaw has an excellent post on the steps you’ll need to take to remove the padlock and gain access to your network settings. Perform these at your own risk - they’re for experienced WM users only. Now go forth and unlock.
