Twitter made its way into iOS 5 and its code may have inadvertently coughed up information about the next generation iPad.
This rumor was started when someone was poking around the SDK and found images in the Twitter.framework that have a retina-like resolution of 1,536 x 2,048. This is far from a confirmation, but we have seen that resolution tossed around before.
Apple may be secretive about a retina display, but its rival and supplier Samsung is embracing the technology. The Korean company recently introduced a retina display for tablets with a 2560x1600 resolution and it looks fantastic. [Techunwrapped via MacRumors]
