As reported before, the current HTC MTeoR (the HTC sales version of the HTC Breeze) ROM has some serious problems including an application lock, which also keeps you away from installing your own certificates on the device, you need to use Microsoft's MSFP.
However - while we still waiting for a new ROM build from HTC which hopefully fixes the problem - the guys over at MoDaCo have found a way to get the device unlocked anyway.
Basically, it includes the installation of two files on the device and some changes in the device registry. However, if you follow the instructions (read the first 4 postings), you should get your MTeoR application unlocked as well:
Finally I can group my Start menu shortcuts in folders again, as well as installing some applications (like the automatic keylock) I wasn't able to install before. Well done guys!
