Frank writes (with some inline photo notes from me):
"Just to let you know I've been using this little accessory for a while, it works perfectly. It is a Kingston 32GB Micro USB 2.0 DataTraveler Flash Drive and is nothing more than a normal pen drive that also has a male microUSB end. It works basically on both PCs and in USB OTG enabled devices, such as the Nokia 808, N8, etc.
I got it to test and play with the USB OTG functionality and to make it easier and quicker to transfer photos and videos off the 808 and to be able to share it to my PC or my other smartphone, a Blackberry Z30.
The speed seems adequate and I use it a lot, especially when travelling, to quickly share any photos between the 808 and my Z30.
Thanks, Frank. Comments welcome if you've tried this gadget too!
