At this time, you cannot officially put WM6.1 on it as it has not been released for the 750. The only 6.1 out there is a cooked ROM someone put together.
The latest OFFICIAL release for the 750 is WM6. You can download the AT&T upgrade from the Palm site.
Or, if you would rather load the Unbranded ROM, which doesn't have all the AT&T crapware bundled in, send me a PM and I'll provide links and instructions.
FYI: Upgrading the ROM will not affect your lock/unlock status. |
