Now that's really funny...lol...
Indeed we have bluetooth problem but don't know exactly abt wifi as i thought it would be a hardware-specific limitation.
I downloaded u9 roms so i can grab newer files or reengineer it to use with a70 but the bloody rom is in exe n i m not able to extract contents from it.
its easy to extract the system.img and boot.img ..
In Windows, run the ROM's .EXE file till it gets to the first dialog. Stop there but don't close the window yet.
Go to Start->Run and type: %TEMP%
When the folder opens, search for Rom.zip (use the "magnifying glass" Search button)
Copy Rom.zip to your kitchen's original_update folder
