Accessible Cell Phones

Since my wireless service no longer offers a network that’s compatible with my PDA modem, I’m exploring cell phones with text and email capabilities like the Nokia 6800 (one bad thing… no built-in camera… pooh!). offers the latest information on developments in the wireless industry from an accessible perspective.
One thing that’s not clear is references to hearing aid compatibility. Does that mean it is compatible with a cochlear implant? Cochlear talks about it, but not specific brands (understandable). I used a loopset with my hearing aid, which shut out all the static so I could at least know when someone answered the phone. Will any loopset work?
