I don't think that's correct. In the picture of figure 5 that I attached in my post, it shows the accelerometer address as "0x18". Also page 61 of the datasheet states:

The default I2C addresses are:
> Accelerometer:
SD01 pin pulled to 'GND': 0011000b (0x018)
SD01 pin pulled to 'VDDIO': 0011001b (0x019)
> Gyroscope:
SD02 pin pulled to 'GND': 1101000b (0x068)
SD02 pin pulled to 'VDDIO': 1101001b (0x069)
Is there a reason you think it is $30?
