So, i want to do some pranking soon but i have no idea where i should start (well, aside from plugging in random numbers and seeing who picks up), but the only phones i have readily available are my house phone and my cell phone (which are both horrible for this thing, seeing as the calls can be traced to me). What would be a good starting point for pranking and light phreaking?'
EDIT: Note that i have done plenty of reading off of Artofhacking, but that's all horribly out of date.
