Having no led notification light means there is no light that blinks when you have missed a call or text. And I believe that they will release an update so the Nexus S can record in 720p.

Also rooting is like jailbreaking an iPhone. Although you can do much more than an iPhone. It gives you Superuser access to your phone. Which literally means you can change every aspect of your phone. Although if you aren't very familiar with smartphones I wouldn't recommend it. It can be very complicated.

And in my opinion the Nexus S is a much better device than the dhd. It has an amazing super amoled screen and the dhd screen looks horrid compared to it. Also the Nexus S has has a better gpu by far. Which is a must if you plan on using your phone for any graphic intensive games. Also the Nexus S will take much longer to go out of date than the dhd. Overall the Nexus S is a much better choice.

 

The Nexus S' camera hardware is not capable of recording in full 720p. It lacks an additional chip that allows for high speed processing of the image before it is bussed to the system. It is possible, however, that the modding community will either come up with a method for recording in 720p at 15fps, or a hardware mod in which the actual camera is swapped out with one that is capable of full 720p recording.

I personally wouldn't hold my breath for either, but to be honest, the 720x480 resolution it records in is still pretty great quality compared to other Smartphones.

 

Wow I had no idea I thought it was like the Galaxy s phones where they were able to enable it with software. I had no idea it was missing proper hardware.
