Yeah, tell me about it. On a slightly different topic, I bought an 80gb PS3 at a store in Greenhills called Rockfire. Long story short, the PS3 was defective and I couldn't use it even once. I brought it back to get replaced, and they not only refused, but the wife of the owner of the store got so angry that she attacked me. SERIOUSLY. I've NEVER heard of anything like that happening. And this was a permanent store with a business permit, not just some stall. She even did it again in front of a security guard! I filed a complaint with the Greenhills administration, reported it to the police, and sent a letter to the Department of Trade and Industry requesting an investigation. I have a slight bruise from the struggle. I would have sued the ***** if I weren't leaving the country too soon to go through the lengthy legal process. So, yeah, if you do go back to the Philippines, avoid a store called Rockfire in VMall, 3rd floor!!
I'm using Optus (my Australian provider) on roaming and Smart on another phone (my parents keep an extra line open for when one of us kids comes back to visit).
