In another sign of the impending release of an official Mango update, an official unbranded European ROM for the HTC 7 Mozart has been leaked, labelled RUU_Mozart_S_HTC_Europe _4.06.401.00_5.69.09_ RELEASE.exe.
The ROM brings the device up to :
OS Version: 7.10.7720.68
Radio Software: 5.69.09.05a_126.96.36.199U
Bootloader Version: 4.6.2250.0(129193)
Of note is that the ROM should not be used with devices which have HSP/SPL installed, and appears to be locked, so we suggest users should just look and not touch, and wait for the official update, which may just be weeks away.

Thanks Vitaly for the tip.
