I downloaded Blade III ROM from ZTE's website and deodexed it and zipaligned and I tested some files on my ZTE Blade and some on my Galaxy Nexus..
For me the best app from Blade III is the "Full Share" (DLNA) that can share files via WiFi to another devices e.g. PS3, PC, iMac
and it can watch the files from PCs, iMac, and from another devices that have this app, etc.
I was only able to watch .mp4 videos and AVI videos didn't show nothing but at least voice works with .Avi files..
App is in the attachment
