[Q] full unlock for my Htc 7 Mozart... (perhaps n00b qn) - 7 Mozart General

Good afternoon all,
Firstly, apologies if this is a bit of a n00b question, i HAVE googled and searched these forums but have found some convoluted, old or confusing information and would like some straight and up to date answers if possible please. I have quite a complex ANDROID history, and flashing, unlocking, S-OFF-ing phones to me is straight forward enough but having moved to WP7 recently i feel a little out of my comfort zone.
My Device:
Phone Model: HTC 7 Mozart T8698
Windows Phone 7.8
FW revision number: 2250.21.51303.401
HW revision number: 0004
Radio SW version: 5.71.09.02a_22.51.50.21U
Radio HW version: A.102.0.D4
Bootloader version: 5.13.2250.3(135167)
Chip SOC Version: 2.2.5.0
Judging from the info above, i can work out that for a FULL unlock i need to downgrade the bootloader (i think)... If I manage to do this (using posts on these forums, a Y-cable, SD card, SD card reader and other magical bits of software) then what are the next steps to obtaining a Full unlock (and being able to install apps via side-load or XAP files)?
I am not bothered to have a custom ROM if I don't have to.
Also are there any NEGATIVE sides to having downgraded boot-loader, unlocked ROM etc? WP7 is great and I don't really want to upset certain features if I can help it!
Again, apologies for certain n00b type questions, i just hope that you understand that I haven't just dived in and asked silly questions, I HAVE tried to research already, but came up with confusion!

Hi, I actually found your post last night and dived straight in, managed to get Dynamics 2.0 on my phone with HSPL 1.30 installed. (Thanks to follow)... only issue i have now is (seeing as Im a WP7 n00b) that I cant seem to work out how to install XAP's - i've tried emailling them to myself, and placing on a google-drive then downloading with the google drive app, and finally pointing IE on my phone to said XAP... none of these seem to do anything for me... am I missing something?!?!?!

had the same prob mate
install this "vm_web.exe"
http://www.microsoft.com/en-us/download/details.aspx?id=13890
let it install (will require a restart) let it finish
then click windows start button scroll down to "windows phone developer tools"
the click "application deployment"
make sure u have zune up aswell then browse to your xap u want to install then click deploy
when finished look on your phone slide to the list and it should be there waiting for you

Just installing now, just a quick note for you... vm_web.exe is only compatible with Vista & 7, I am running XP SP3 on my machine so had to follow the (simple) instructions at this thread:

Will report back with how it goes once its installed...

Ok, all installed, rebooted and kids picked up from school... Now all it seems to have installed is the following folders in my start menu:
Microsoft Expression
Microsoft Silverlight
Microsoft Silverlight 3 SDK
Microsoft Silverlight 4 SDK
Microsoft Visual Studio 2010 Express
Microsoft XNA Game Studio 4.0
No sign of the things your directing me to? Im VERY confused now... Did I install the correct thing?!?!
