At first, I thought that this is a typo error but when I saw the difference of specs and the product code versus MyPhone Rio Craze, this indeed (if based to Lazada PH app where I have these screenshots) as the official 9th MyPhone Rio.
The Rio Craze 3G has dual sim, Android 4.4 Kitkat, 1.3 GHz dual-core Mediatek MT6571 processor, 3G capable, 3.2 MP rear camera, 1.3 MP front camera, bigger RAM and ROM compared to Rio Craze at 1 GB RAM & 4 GB ROM and 1,300 mAh battery.
Based on Lazada, it is currrently on stock and this can be yours for Php 2,599
