Hi, I bought a $30 M.I.C CF card reader last year and recently upgraded from ios 4 to 5.01 on the iPad 1. I was testing the CF card reader and it doesn't work anymore. IOS 5.01 says the device is not compatible. This is the device as reviewed in: http://robgalbraith.com/bins/content_page.asp?cid=7-11412-11522 Do any card readers work on iPhone 4s or iPad 1/2/3? Thanks.
