1) Are there any working hacks for getting FM radio reception on the
neo 1973? Even the $35 (total for the unlocked phone that will work
with any network) Nokia phones have FM reception in india. This is a
must have option for the Neo to sell in India. Most phones use the
earplug cable assembly as
Silicon Labs SI4700 and SI4701 are entire FM tuners on a single
chip, and they are tiny. I have their USB FM Radio and I use it
every day on my PC, and I believe the same chip is in my Sony
Ericsson phone. This is the one that uses the earphone wire as
antenna, although it can be separate, as is

Well I mentioned both, and they are separate chips.
There is plain FM, FM with RDS/RBDS, AM/FM
and also FM

I am planning to make some PCB boards with the SI4701 and
minimal parts on them in the future, will be sold on ebay
(I have surface mount reflow oven).

Implementing an FM sender would however make the Neo hard to sell on
markets where personal FM transmitters are illegal (however weak the
signal is) such as Sweden. At least it was still illegal when I was
living there.

ahm - we're talking

Georg,
My original plan was to design a generic add-on board for
embedded single board computers that includes an audio
codec, FM tuner, and optional text-to-speech. I still have
that plan but may make several variants on this, I have lots
of interest in mobile audio
Georg,
The amazing thing about these Silicon Labs parts is that they require
almost no external components. For example the SI470x FM tuners
require a crystal and regulator, that is all, they can use headphone
cable as antenna (as is done in most phones now), and they have
stereo analog output

This could also enable some really cool speakerphone abilities, as long as
we can then filter the audio input to remove the echo
There is an interesting speaker phone codec made by cirrus logic

They are in stock at digikey
