A week ago I rooted my Xperia Mini Pro SK17i cyanogenmod 9, everything works pretty well, just that some of the things that I got to compromise and the biggest was 'Sony Bravia Engine', it is something that you don't find too much regret unless you have experienced it.
Things really look unpleasant after sacrificing Bravia Engine. Before rooting make sure that you don't lose some customization or features that you like which is from manufacturer side.
Best of luck with your root. |
