How to delete swf files?

[netlogger]

Thanks fror your answers,
But my phone changed due to warranty. (there were some dead pixels on old phone's screen).
Now it's a R4EA031-cid:49 phone.
all I have got is for Cid:50 phones. Now I'm searching for new ones :(
now with this Cid:49 phone; is there any way to revert the patches that I made?
( I didn't pacthed yet, I want to patch after I know everything to go back :) )
