A dude on a different BB forum said he had this OS on a replacement pearl he got yesterday. So far he hasn't discovered any new features though (just the usual "smoother", "more solid" spiel). I heard somewhere that Tmob was due for a new one any day now. Anybody know more? And I forget how to see what OS is on the phone.
08/15/07: Edit to the above original post:
TMobile has now released package v4.2.1.168/app v4.2.1.103 plt 2.3.0.82
It is available here:
TMobile.com
Instructions for loading this OS on ANY carrier's 8100:
Instructions for installing:
1. Make sure you have the latest version of Desktop Manager installed. It's 4.2 SP2. (The version listed on the TMo site is quite outdated, I don't recommend using that one.)
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.
