The Sciphone Dream G2 is a [wiki:MT6235] based phone running UI software to mimic the look+feel of Android.
There is currently an u-boot and Linux port for the MT6235 underway, the primary development platform is the Sciphone G2.
OsmocomBB does not yet support any Mediatek chipsets, so this phone is not supported by OsmocomBB. Nonetheless, we
expect to have support for it at some point in the future.
More information on the hardware of the device can be found at [http://en.qi-hardware.com/wiki/Sciphone_Dream_G2]
You can make a serial cable by sacrificing the headset that comes with the phone, by swapping the pins inside the connector.
The JTAG port of the MT6235 is accessible on the phone PCB, see the attached picture.
You can use [http://openocd.berlios.de/web/ OpenOCD] along with the attached configuration file ([raw-openocd_mt6235.cfg]) for debugging.
Like all Mediatek MT62xx !SoCs, the phone uses the [wiki:MTKRomloader].U-Boot
