According to an SMS going around:

Pls switch OFF all ur handphone 2NITE.According to Metro TV,an international news, there will be a BIG RADIATION WAVE circulating thru the handphone towers at 11PM 2nite which is very DANGEROUS to humans. Pls inform ur friends NOT 2 keep their phones with them. Pls FORWARD.

"gud pm! 2log na me!"

I guess the telecommunications companies have had enough of Senate President Juan Ponce Enrile badgering them about their fishy prepaid load accounting systems and their non-stop SMS ads.
