I did. It was great, I could store tons of videos and pictures on it off my sd card and organize them in ifile. I could clear my sd card while traveling and keep shooting. That is, until I upgraded to 4.2.1. Now it doesnt work. Very lame. I would suggest that if you are on 3.2.1, stay there if you want to use the SD reader. Maybe apple will fix it for 4.3, I dont understand why they would change it. So now they are selling an accessory that doesnt even work with the latest firmware... Real sweet.
