hmm ok, than i have do maybe a another plan. Maybe a solution without the internal batterie and only the 3200mAh accu.
Or a thin board I can put between the internal battery and this connected to the external accu. But the question is what happens when you connect two batteries in parallel. If both batteries loaded properly?

I wouldn't be so resolute. People connect batteries in parallel all the time. See for example this thread, it contains diagrams of how to do it with the N900 batteries (the trick is to use the chip from only one of them). And my old laptop used 8x18650, four times two in parallel.

yep. you cant use 2 different battery cells together (lipo/li-ion/). its killing smaller battery and they do not charge in balans! smaller can burn..

hi! nice work so far!
i wonder how the power management will handle this... usually (i.e. when charging via usb-board) the phone stops charging when the internal battery is full... be sure this also happens when charging via those connectors or you'll end up with some pretty expensive fireworks...
also be sure you don't run into trouble when connecting the phone to a usb-port while this other half is attached (would be double-charging, wouldn't it?)

If the internal circuitery requires at most 3.3V, with 0.5V difference it could just make it if it's a 'low dropout' type. However I'm afraid that as the input is supposed to power everything AND recharge the battery, a 3.8V source would be considered under the minimum and would not be used at all.
