Confirmed working on a ZTE Grand X from Virgin in the UK
Worked beautifully after second attempt - Very happy, donated a few bob to say thanks!
To root follow instructions over at XDA
I am officially a happy bunny!
[WARNING] This worked for me but isn't confirmed as it appears to have bricked someones phone. AT YOUR OWN RISK, GENTLEMEN. [/Warning]
