How To Unlock GPRS Settings on BlackJack II with Windows Mobile 6.1

Now that Samsung has made the Windows Mobile 6.1 ROM upgrade official for the BlackJack II, I should take a minute and remind everyone about the post I made a while back that helps you to unlock the carrier networks settings. This is a new feature that was added to Windows Mobile 6.1 by special request of the carriers who are looking for ways to reduce support calls from people that toy around with the network settings and don’t know what they are doing.

Of course, anyone with a unlocked BlackJack II that is looking to use the phone on a different network will need to unlock these settings and modify them to match the settings for their carriers network.

You can read the original post with full details on how to remove the lock over here. And to everyone that’s upgrading, enjoy the new ROM and while you’re flashing your device, why not take on the No Reboot Challenge. What better time then right after a fresh and clean install of the OS.

Update #3 On The No Reboot Challenge

The No Reboot Challenge is growing in popularity! I would like to welcome Bambi from Windows Mobile Cool to the challenge. So we know have Chris Spera, Dieter Bohn, Bambi, myself, and all the readers from each site that have joined in which is simply amazing. I also want to thank Tariq from My Today Screen for posting about it on the site – I wonder what it’s going to take to get Tariq to join in on the challenge? And let’s not stop there, I would love to see others joining in as well.

Now down to the details; It’s been 15 days since I started this challenge (August 19th) and so far things have been smooth sailing. Cellular reception has been top notch, there’s been no weird missed calls, and no abnormal behaviour from any applications – aside from IE Mobile using 25MB. Thankfully it’s down to a reasonable 5.6MB. Windows Mobile has actually done very well at closing applications that are left open in memory. I regularly use the Task Manager to switch between applications and I have noticed that Windows Mobile will shutdown applications that haven’t been used in a while if it starts to get concerned about memory usage.

The phone was put into flight mode over the long weekend. My wife and I took the kids to the cottage and there’s no cell reception unless I put my feet into the lake and hold the phone just so. Instead of leaving the phone radio on and hunting for signal, I simply dropped it into flight mode and left it on the kitchen table. When we left the cottage I turned the radio back on and it picked up a signal pretty quickly and everything returned to normal. As a quick aside, when I did this a couple years back with a 2003 SE device, it didn’t come out of flight mode as easily. Something has changed over the years, and for the better too!

With everything running so smoothly, I think the only thing that could knock me off course is Samsung releasing Windows Mobile 6.1 for the BlackJack II. Oh, and lookie here – they just did. D’OH! Must resist…
