Instructions for installing:

1. Make sure you have the latest version of Desktop Manager installed. It's 4.2 SP2.
2. Download the above file to the PC then install it to the PC by running the file you downloaded.
3. Locate the vendor.xml file and delete it. It's located in C:\Program Files\Common Files\Research in Motion\Apploader
4. Plug in BB and open Desktop Manager. You should be prompted to upgrade.

The process takes about 45 minutes to an hour depending on how much data you have to backup and restore during the process. Once it's done loading the new OS it will reboot (it may do this twice during the entire process.) You will see a white screen with an hourglass for up to 20 minutes at a time while the DM says "waiting for initialization." Don't unplug from the PC & Don't remove the battery unless the spinning hourglass has been there for 30 minutes or more. If the hourglass has been spinning for more than 30 minutes continuously you will need to wipe the device with JL_Cmder (close out of Desktop Manager during this process.) You will then end up with a white screen with small icons and an error code number like 507 or 543.

If you end up with a white screen with small icons and the number 507/543, simply connect to DM again and run application loader again and it should load the OS to the device.

Can this one be loaded on an 8800?

Wirelessly posted (BlackBerry 8700g: Opera/9.50 (J2ME/MIDP; Opera Mini/4.0.8993/58; U; en))

I don't believe the 8820 software works on the 8800.

No.

Excuse the novice question but wouldn't the BB 8820 be shipped with the most current software? If not, what is the difference between the newest and the one before and is it worth the upgrade. I just bought an 8820 but haven't received it yet...

Though it may have this loaded as the native OS via AT&T, other carriers may not have this OS version, and can make use of it using the information contained within these threads. =)

Hi Spencer, is this OS specific to AT&T network?

Any 8820 OS can be loaded on any 8820. Just follow the instructions in the first post.

What problems does this update fix?

The carriers usually choose not to post release notes.

before I do any think I am checking my BB 8820 and it has V4.2.2.169 and 2.4.0.67
what do I have to upgread?

As an FYI, I downloaded this package and attempted to load it over the SmarTone/Voda package released earlier this week. The DM indicates the SmarTone is a later package. Is this true?

Compare the version numbers. On your device look in Options >About.

John,

I am a bit confused by this. Perhaps you can clarify it for me. I have d/l both the SmarTone and AT&T 8820 OS software identified here. They are:

SmarTone:

Applications: 4.2.2.160
* Software Platform: 2.4.0.70
* File name: 8820CJK_PBr4.2.2_rel287_PL2.4.0.70_A4.2.2.160_Smar Tone_Vodafone_(Voda_HK).exe

and AT&T

Applications: 4.2.2.169
* Software Platform: 2.4.0.67
* File name: 8820M_PBr4.2.2_rel305_PL2.4.0.67_A4.2.2.169_AT&T.e xe
* File size: 79.88MB

When I look at the 8820 >Options>About, I see the 4.2.2.160 (Platform 2.4.0.70) currently loaded on the device.

When I looked at the AT&T package, I see the version should be 4.2.2.169 (not sure what the differences are). As the AT&T version at 4.2.2.169 is higher than the SmarTone 4.2.2.160, I expected to be able to load the AT&T version, but the DM indicated the AT&T version was actually a step down and warned me before I loaded it. I can only conclude the platform 2.4.0.70 (SmarTone) is actually higher than platform 2.4.0.67 (AT&T) and the version on the device is not what DM uses. What am I not understanding? Thanks for any insight you may have.

Is anyone else having problems downloading this software onto there computer?

Help! those icons that I moved to folders (created by me) all disappeared. This is after I upgraded to latest AT&T OS.

I cannot those apps anymore. Any ideas?

Thanks

Have you tried changing themes? It seems to be a common occurance after moving icons.

Thanks John. The icons are back after I did a reboot of the BB.

I'm trying to get my hands on a 8820 to use both with my ATT acct and while In Africa on my Glo (local gsm account).

Do you know if the ATT model is unlocked or do we need to generate a unlock code. ?

Thanks

The only difference between the AT&T model and the official RIM one, is the AT&T one has their own software and is locked. You will never get an AT&T branded (or any other carrier for that matter) device that is sold unlocked by the carrier.
