I own a Motorola Fire XT myself and I thought it would be of good help if I compiled the resources for this phone together in one page with links for other people to use.
All tweaks and methodologies mentioned are because of the hard work of a number of developers. I do not claim any ownership or responsibility to the stuff that I list here. They are not mine. I just happened to search the internet for my own phone and found these links. Respect the Devs. Not that we have this information across, let’s get started.
These links worked perfectly for my Morotola Fire XT.
Rooting Motorola Fire XT:
Note: Rooting will void your warranty, unless you unroot back.
Increasing Phone memory on Motorola Fire XT: (using Link2sd) to be done after rooting
This guide is written for Xperia, so skip directly to "4. CREATE SECONDARY PARTITION" section and follow the instructions from then.
Remember: You have already rooted your phone, don’t do the rooting method of Xperia phone again and brick your phone. Have some common sense.
Use the Auto-link feature of Link2sd and automate moving the apps to SD cards second partition. This will act like your internal memory. Good luck.
