Change your e-mail signature, here is a how to for your iPad 2 and iPhone 4!  Don’t be one of those people who leave the default ‘Sent from my iPad’ signature on all their messages.

Will the launch of the iPhone 5 come in Fall of 2011?  That’s the rumor!

It’s well known that Apple releases a new version of the iPhone every summer but with the release of the iPhone 4 on Verizon just a few months ago, it’s likely the device will be delayed until the Fall. Here’s why: 

You can take a screenshot of whatever is on your iPad 2 / iPhone 4 by pressing and holding the Sleep/Wake button (top right) while quickly pressing and releasing the Home button (bottom center).  The screenshot will appear among your Photos.  This function is awesome if you receive a really funny text that you want to pass along (in all it’s glory) to your friends.

Notice your iPad 2 / iPhone 4 didn’t come with a large printed user manual (that’s just not Apple’s style).  The guide is available in PDF from Apple’s Web site, or you can read it in iBooks (available as a free download in the App Store). Make sure to download the manual for iOS 4.3.

Now your iPhone can accept Amex, or other credit cards, with Square!

The iPhone is now credit card compatible.  A company by the name of Square has designed a credit card reader that plugs into the headphone jack, enabling you to accept credit cards and debit cards on the fly.  Square then transfers daily deposit to your bank account. 

Surfing on your iPad 2 or iPhone 4 and curious what’s on the other end of a dubious link?  You can check the URL destination of a word/term before opening it.  Simply touch and hold down on the link.  It’ll show you a pop-up like the one above.

Want to save battery life on your iPad 2 or iPhone 4?  Switch up the data push frequency.  

A major gripe of non-adopters of the iPad is its virtual keyboard.  Although it works great and with little practice, you can type equally as fast on it, some people simply prefer physical buttons to press. Logitech and ZAGG had an answer in mind when they teamed up to create this thin, eye-catching keyboard case.
