Smartphone with additional peripherals

[Vindhyachal Takniki]

I need to make a smartphone like device with some additional peripherals like ethernet , some application specific interfaces.
Device should run android on it, it should have SIM in it, internet connectivity, camera also, usb connectivity on PC , touchscreen , speaker; basically all features of mid segment smartphone.

For addional peripherals, which are to be handled by apps in android, I am planning a separate board for them which will interact with beagle board(which is running android) via some comminication protocol.

How should I proceed?

I had checked http://beagleboard.org/project/hbp/ , but its further link don't get opened.

Which board should I select?

well to be honest beside the Ethernet port which I reckon you could work around I see no issue with using a phone
for the Ethernet port you could write an app that uses the USB out then make an Ethernet connector board...... or you could try building one from the myriad of mini PC's coming out
the odroid-c1
banana pi
Minnowboard Max
there are others... but will let you find them
