I've successfully rooted my HTC Desire. Installation of Gingervillian ROM in the rooted desire is also successful. I followed the following posts of SUroot. Thanks a lot SUroot to make this thing too easy to say. http://androidforums.com/desire-all-things-root/221212-faq-rooting-updated-19-03-11-a.html http://androidforums.com/desire-all...g-unrevoked-windows-published-19-03-11-a.html I followed the process described by SUroot line to line. So, I faced no problem and fortunately I didn't found any unusual things during the operation. I already restored all the apps (by Titanium), SMS (by SMS backup and restore) and contacts (by android's Import/Export feature). But.. It seems a little bit slower response than previous. I'm disappointed after checking the score (only 711!!!) at Quadrant Standard benchmarking app. It would be very helpful for me if I get some suggestion to improve the performance of my Desire driven by Gingerbread.
