image transfer from DSLR to BlackBerry in the field.

Hi,

I wonder if anyone is aware of any device which would allow me to connect a range of DSLR cameras to BlackBerry handsets while out in the field. This is to allow images to be sent back as soon as they are taken from a variety of locations. the photgraphers would need to carry everything with them and for the process to be as simple as possibe. I have looked at Belkin USB anywhere and various other USB OTG devices but they generally get terrible reviews.

I am not interested in a wireless solution., i currently use microSD to SD adapters.

Thanks for your time.

Rob
