^^ You can undo the root...so shouldn't be a problem.
Also w/o rooting , you wont be able to install a custom recovery and a full backup of the whole factory ROM wont be possible.
Also I suggest you guys to spend 2 hours on the Blade TE thread and another hour at Modaco...it will be good and the modding you can do after that will be limitless. Please dont use this thread for any more queries, the dedicated ZTE Blade/Orange SFO/Dell XCD 35 thread is better suited for that and you will get more timely help as well
