Windows Mobile 6 Not Compatible with all Treo 750s?

I just read the following on GearDiay:


I saw this over at Mobility Site and wanted to pass along the happy (or not so happy) news. The WM6 update for the AT&T Treo 750 is now available for download. The update SHOULD go well for those of you that can actually download it. Puzzled..? Read on my friends…

I pulled this down last night and have a version that got out before Palm put in the serial number validator on their site; but it makes no difference for me (more on that in a sec…) In order to download the new OS for your Treo 750, Palm requires that you enter your serial number into a validation field on their site before the download starts. The validator insures that only AT&T 750 owners get the update and can install it on their devices. Makes sense, right? If you were to actually get this update on any other Treo, it would brick the device. Thanks for the help, Palm, you’ve saved me from myself…

However, many people who have tried to download the software are running into 2 interesting problems:

Invalid Serial Number
Despite having a Cingular branded 750, I (and it appears many legitimate 750 owners as reported on AT&T’s own forums, XDA Developers, and other major Treo boards), many users can’t download the update.
Invalid Software Version
I have software Version Treo750-1.10-CNG on my device. The updater wants Treo750-1.13-xxx on your device to install the ROM upgrade. Absence of version 1.13 makes the updating think you have an invalid device.
So even though I was able to get the updater down without my serial number being validated last night, the software won’t install. Oh goody…

I will be going to the AT&T Corporate Store in Meriden, CT to get some more information on this possible problem.

UPDATE:Apparently, installing the new ROM via the Mini-SD card is the workaround for having a pre-1.1.3 Treo 750. I will look for instructions and post them when found.
