Apple could be ready to ditch the 30 pin dock connecter it uses in all of it’s iOS devices. This would make some room for better hardware.
An Updated “micro dock” could make room for bigger batteries, 4G radios, and other components far more important to the iPhone and iPad in a PC free world.
Apple has made some components in their iPhones smaller for thinner designs. Like the micro sim to make a thin design for the iPhone 4 for more hardware improvements and a thinner design. Could we see a smaller dock connecter or even better wireless charging? This could be a problem for some people and case makers as all cases for these products are based around the 30 pin dock connecter.
This comes from popular rumor site iMore.com which has great iOS news and rumors. They are what we are basing the iPad 3 launch date off of. March 9th.
