In April 2012, Apple started shipping a slight variant on the iPad 2 that remains for sale even as the third-generation iPad has become the mainstay of the line. This new version of the iPad 2 — labeled internally as “iPad 2,4” — uses a 32 nanometer version of Apple’s A5 chip that replaces the 45nm version in the previous iPad 2 model. The processing performance is the same, but AnandTech is reporting that the 32nm model has notably better battery life (and a lower manufacturing cost). Alas, there is no way to know if any given iPad 2 uses the new chip without running an app that reports on the internals. follow link
Move to Top Shortcut in iPhone
On an iPhone, flicking all the way back up to the top of a long Web page can be a real drag. Instead, a single tap on the status bar moves you to the top of a page. (The status bar is where the clock is.) This tip also works in other apps, like Mail, Contacts, etc.
