Revolutionary achieved radio S-OFF for Sensation (among other devices) which means you can practically do whatever you want with your phone (like actually owning it..). This means it makes it vulnerable to all sorts of schemes including sim-unlocking. This can be done various ways (check forums), but I find the following quite efficient and easy to do!
Requirements: owning a Sensation S-Off’ed using this;
1. download
this file and put it on the root of your sdcard
2. reboot your phone in hboot and let it do its job: load the file you’ve just downloaded from sdcard and run it. That file is a diagnostic utility and serves various purposes given various conditions.
3. you’ll enter a menu from which you can choose to check your device’s info or reset s58 data.
4. Reset s58 data. This actually resets some things including your sim-lock status.
Now you’re free to go! Bear in mind, though, that in certain circumstances you’ll lose your data connectivity or network signal. You’ll just have to check your APN, network type & so on; I guess this varies with each case.
Credits go to you all, XDA community, but best you should thank

WARNING!!!
Backup all your settings/apps/sms/etc, network unlocking by using this method also involves
wiping your data!
