No - skip the "like you're 5" tutorial's way of doing bootloader unlocking as it does an unofficial unlock which can result in 3G reboots.
Back then that was the only way to unlock the bootloader but there is a much better way now.
Unfortunately some of the info/links/guides/tutorials posted here are out of date and not up to speed with more recent ways of doing things.
Instead refer to the link that I posted for details of how to do an official ICS bootloader unlock using a code from Huawei or using DC Unlocker (may not work for everybody).
Bootloader unlocking must be done on stock ICS.
The link that I posted should be a good pointer to where to find the info to root, unlock bootloader, install CWM/TWRP, install ROM etc.
Hope this helps.
