Would love to be able to attach a SD memory card reader to my Thunderbolt so I could download photos taken with my digital camera to my phone's gallery. Any way to actually do that?
You could email them to yourself...
Is there no microSD slot? You could hook it to a computer via a USB cord and transfer files that way (when you hook it up, typically, android asks if you want to mount the sd card, the response would be yes)
Nope. USB ports on these devices are not for hosting USB peripherals. They're certainly not designed to power USB peripherals. People already complain about battery life as it is.
