Nalito lang ako sa question, "Saan ba bibili or Anong bibilhin ko, iOS or Android?"
If san bibili, iOS/iPhone are sold in PowerMac outlets, while you can probably get the best deal Android phones by buying directly from phone markets (inside Malls, online shop, etc). If anong bibilhin, depende kung san ka komportable, iOS/iPhone is more user friendly than android IMO, but Android offers more advance features than iPhone. You also have to consider your budget first.
