I have a device like this. Definitely not the iphone. Its the blackberry pearl 8100. So far, its working fine. Nilagyan ko ng 1 gig micro sd, I saved about 100 songs and it plays good. Wala nga lang syan video recorder, pero it can play videos. The camera is mediocre, pero its better than nothing (1.3 mp). All the apps are fine, and I like it that I can do presentations using my phone as the control.
Downside lang is, what if mabagsak ko (wag naman sana). Its pretty pricey, but its worth it.
