I finally got around to flashing JAC's xROM 2.1 on my MyTouch while I wait for my N900 replacement and I hate how slow it is...but I miss 2.1 quite a bit after returning my Nexus. It would be nice to have little option in the boot loader called "Root" in both the iPhone and Android devices, followed maybe by a "Carrier and Software warranty will be voided CONTINUE, ARE YOU REALLY SURE" then you get root.
