How to buy a nrf51 Beacon Module with 3rd revision chip

Hi,

As explained in devzone.nordicsemi.com/.../ I want to interface my Beacon to a Invensense sensor with I2C. I'm having a hard time about using the I2C drivers/examples, as it seems previous versions had some bugs, and some old ones don't work with the softdevice.

As an answer to my previous post, it seems 3rd Revision chips in SDK 9 have examples and new drivers. The problem is that the Beacons I bought in Jun 2015 all have 2nd revision nrf51. It seems some Beacons modules have the latest 3rd revision chips, but how can I be sure to get those when I order through sites like Digikey?

Any help on this or even any working example of I2C on Rev. 2 chips that works fine with the softdevice is appreciated.
