Also I noticed it doesn't look like they give you headphones or an SD card. The Infuse came with the HDMI connector and a 2 gig SD card (according to the review I read). Sprint doesn't list anything other than the phone and the charger in the box. Guess my Sprint Pre headphones will live on.
I use monoprice all the time. This is $15 for quantity 1.I think the Samsung adapter will be $29.99, but I found this one for half the price and it displays another micro USB port for charging when watching movies and such.
For only $13.51 each when QTY 50+ purchased - Micro USB to HDMI MHL Adapter - Black | MHL Adapters
