Patch can not damage your phone to its death,just to its not working...
That can be undun by flashing the main firmware up again...

Patch is text file that is saved in .vkp name opened with notepad...
Every thing that comes ahter the sign ; will not afect the patch it is only
the description of patch it self...

And finaly, if you havent patch your flasht phone you havent seen the
"cool" things that your mobile hardware can do...

So patch away...:)

and hapy patching:)
