[TUTORIAL] Desbloquea tu teléfono (Jailbreak), Previene que se vuelva a bloquear. (NO FUNCIONA EN WP 7.5 MANGO)

8.2 Mango update:
There's already a BETA version of Mango out there which is intended for developers - but with some additional steps you can also install it without being a developer (and even without having a developer unlocked phone)! This update WILL REMOVE YOUR UNLOCK AND DISABLE THE USE OF HOMEBREW APPS! -> You won't be able to sideload apps anymore and you won't be able to use tools like registry editors and file explorers! Basically, if you want Mango update + jailbreak you've to prepare your phone while running NoDo (or earlier). To explain the process shortly: There are official apps which read out files information and apply changes to the phones registry. Just imagine a connection managing application which has got one file for every single provider containing informations like APN, Passwords, ... . Okay, so while you're on NoDo you can add your own files to this application - but these ones won't contain information about a provider. Instead they'll tell your phone to change several registry entries. And example would be the "Connection setup" app for HTC devices. People can add a .provxml file to the app. Then they update to Mango with loosing the developer unlock but not the file. On Mango they open up the "Connection setup" (<- You have to use this official tool - sideloaded apps won't work at that time as you're not developer unlocked yet) and can see the entry of the .provxml: There will be several networks to choose from (e.g. "T-Mobile", "Vodafone", ...) and also a entry called something like "Developer unlock". Well, this is because of the .provxml file. Then you just have to choose and run this file and the changes will apply - your phone is unlocked again! Just search and you'll find much tutorials here on how to use provxml method on HTC, Samsung, ... devices. I unlocked my Omnia 7 running Mango BETA v2 using this method.
