I use the digital hdmi adapter from apple extensively with both mt iphone4 and ipad2. Right now I have to take the case off the iPhone to use it. I also find that the shear bulk and weight when the hdmi and power cables are detrimental to ease and comfort of use and for some functions it just does not work to have my iPhone/iPad sitting on a table. I have been looking to find an extender cable but most I have seen so far tend to have reviews indicating either no charging or other function not working. Any suggestions would be appreciated.
