Actual stage is earpiece integration. I search for a small earpiece and I find one on nokia 2630 which also donated the antenna and mike. Placing this earpiece under front cover is a really hard problem because the place is very crowded and i must measure twice before cut so next update will be made after completing this job. Don't search thread daily.( this weekend I will go with my enduro bike on hills and next week I will go on easter vacation so i have limited time for this job)

For antenna I find a solution and will be placed inside speakers assembly. I have a small problem - finding thin coaxial cable ( 1mm ) for connecting the antenna.

i saw on schematics, uart3 have 2.8 V transceiver ( adapter ) so telit module can be wired directly on diagnostics pad
