Only rooted a couple of months ago using the one click method, absolute breeze thanks largly to this sub-forum. 
Had been running GV, which I found excellent compared to the stock Orange Froyo rom
!
Had my eyes on MiUi and had a go with the XJ rom...... Love It!
Anyone on the fence about whether to try it or not, its like the best bits taken from Android and Apple.
Is the XJ rom, the better rom out of the three?
GV had a mod that could disable ads via its 'Villain Setup' is there a way I can do this with MiUi?
Also updating was a breeze with GV, again via its 'Villain Setup' - I noticed MiUi had a similar feature, but I'm worried it will update (when there's an update available) to the stock Chinese rom, will it?
Thanks Dan
