A few minutes ago I needed to check some info about the V902 from Sharp, a VodafoneLive device. I opened the UAprof (http://www.sharp-mobile.com/UAProf/902SH_G001_base.xml) and started searching for the items I needed.
It looks like Sharp has made a new Audio codec: AMR nallow-band.
Apparently it is only supported for encoding. Decoding supports the more famous brother “AMR narrow band”.
I wonder how many companies and sites rely on this blindly…
