After I was using a Archos-70IT tablet with some restrictions for my use cases, I was looking for a new tablet with bigger size - but smaller than 10". Since the Samsung GalaxyTab 8.9" is'nt a phone and does'nt support microSD cards, I was ordering a Samsung GalaxyTab 7.7" .
Here are some tools & adapters (plus sources) and technical information about the 30 pin connector...
