Read Popular Magazines for Free - Playboy!! :D

Digital magazine provider Zinio offers up the current issues of 20 free full-page browsing by iPhone users. However, non-iPhone/iPod touch browsers can also score free access using the User Agent Switcher extension for Firefox or a simple Safari tweak.

In Safari, set your browser to the iPhone user agent in the Develop menu, which you can enable at Preferences->Advanced->"Show Develop menu in menu bar." Opera users have built-in user agent switching for iPhones, and Firefox users can install the User Agent Switcher ">User Agent Switcher, then create an iPhone agent.

Step 1: If you are on a Windows PC, go to apple.com and download the Safari browser. Mac users already have Safari on their system.

Step 2: Once you install Safari, go to Edit -> Preferences -> Advanced and check the option that says "Show Develop menu in menu bar."

Step 3: Open the "Develop" option in the browser menu bar and choose Mobile Safari 1.1.3 - iPhone as the User Agent.

Step 4: You’re all set. Open zinio.com/iphone inside Safari browser and start reading your favorite magazines for free. Use the navigation arrows at the top to turn pages.

Once that's done, switch to your iPhone agent and head to the Zinio link below. You'll get full-page browsing of 20 titles, including UK and Spanish-language versions of Macworld and a handful of mens' magazines. I should note here that Playboy and Penthouse are also offered up (as you might guess from the declarative link title below), so don't follow through if a glimpse from a boss might land you in hot water.
