One of MyPhone kiosks has recently brought one of their Infinity phones from last year in a more competitive price.
As I checked recently in their official kiosk in SM BF Paranaque, MyPhone Infinity LTE is now at Php 4,499. The price is not bad at all for it's specs with Android 4.4 Kitkat, dual micro SIM, Qualcomm Snapdragon 410 quad-core processor, 5.5 inch IPS HD display with Gorilla Glass 3, 13 MP rear cam with flash, 5 MP front cam, 1 GB RAM, 8 GB ROM and 2,820 mAh removable battery.
At it's introduction 11 months ago, it is priced at Php 7,999. You check out my first impressions of the said device here
