Unrooting Mytouch Slide

Ok, I am a semi-noob with this stuff. I rooted my G1 (RIP) and that is my only level of rooting. I do not know how to unroot. My gf just got a slide off of craigslist and its rooted. She cares less for it and wants the stock verison of the phone. I have tried xda forums but their lanuage is way to technical for me. I need a noobish step by step guide on what I need and how to unroot the slide. Please, I need help. Thanks.

tell he its better rooted.. unless she's waiting for the official update.

I believe the mts is easy to unroot.....speak to gozilla or tmobile2lyfe and they can tell you how.....im leaving everything unrootted except my hd2 if i need to tether i'll just use that....

It's pretty easy for the Slide since there isn't a permanent recovery. Here's the latest Slide OTA with some pretty simple instructions.

To get into recovery, turn off the phone and boot it holding volume down + power. I think you should be good from there if you followed the previous instructions.
