I wrote a month ago about difficulties with free Wi-Fi. You will remember that I listed:
1) Shell Magallanes
2) Areas of Robinson’s Galleria

as free hotspots/zones. Now add this:
3) Petron Makati

That’s right, the gas station on the corner of Ayala Ave. and Gil Puyat Ave. (though I still like calling it Buendia). I’ve heard rumors indicating Shangri-La Makati’s lobby to be a hotspot, but I won’t confirm until I check it out with Matus.
