There’s plenty of software programs on the Mac App Store that will allow you to add a signature to a PDF, but come Lion, you won’t need any of them: Preview.app will do it by creating a perfect digital pen signature via FaceTime.

Here’s how to sign a PDF in Preview under OS X Lion.

Darren Murtha sent us this pic of his WWDC wristband — the one Apple hands out if you’re over 21 so you can drink at events.

Murtha, who makes cool apps for kids, thought the wristband that says “If found, return me to WWDC” funny, a bit like the note Paddington Bear has pinned to his jacket (“Please Look After This Bear.”)

Do you think Apple wants the wristband back if it gets separated from the wearer or if one finds a tipsy dev wandering around SF you should return him or her to Moscone Center?

Our heads are spinning with all the new little features that are packed into iOS 5. Our heads also might be spinning from the new “LED Flash for Alerts” feature found under the Accessibility settings which we just enabled. While it currently only works on the iPhone 4, this neat little feature enables your phone to send out a few pulses of light from the LED Flash every time you get a new Text or Phone call.

Apple is the world’s No. 1 consumer of flash memory, passing HP on its way to spending $17.5 billion for iPads, iPhones and other mobile devices. With that number only set to rise, it is very possible that next year, Apple will spend more per year on flash memory than Nokia’s entire market cap.

As the resident dead head of Cult of Mac, I’ve always been a little disappointed with Pop Cap’s Plants vs. Zombies for the iPhone and iPod Touch ($2.99). It’s a great game, but limited compared to the Mac and iPad versions.

Great news, though! Pop Cap has just updated Plants vs. Zombies and not only it it getting some of the features it was previously missing over its brother ports, but it even is getting a feature that Plants vs. Zombies HD doesn’t have… at least for now.

Look, this is total nonsense, so take it with a grain of salt, but Apple’s carrier partner in the United Arab Emirates has just seemingly confirmed that the next iPhone will come with LTE 4G. We say no way.

It’s been about a year since Apple updated its Server line-up with new Mac Pro and Mac Mini Servers. Now, constricting supplies of both indicate that a new refresh is coming… just in time for Lion.

You can’t say Lodsys weren’t warned that Apple was prepared to fight: less than two weeks after the notorious patent troll sued indie iOS developers for using Apple’s own in-app purchasing mechanism in their apps, Cupertino has asked a judge to be allowed into the ring to kick Lodsys’ ass.

Here’s some advice to tablet companies hoping to beat the iPad features: stop wasting your time. The only alternative is to drop prices ridiculously low, like $300, says a Wall Street observer.

Here’s a nice little feature we’ve discovered in the first iOS 5 beta – a great way to skip tracks in the iPad’s new Music app.

Developer Ben Dodson has uncovered some cool stuff inside iOS5 that can turn your AppleTV and iPad2 into a wireless games console setup.

Yesterday, we reported that in the first beta of iOS 5, Apple had removed gesturing functionality from first-gen iPad owners, making it impossible to navigate between apps on Apple’s breakout tablet with iOS 5’s four- and five-finger multitouch gestures.

Here’s the good news. You can get them back. The bad news? It takes a jailbreak to get it done.

Being a Chrome man, I generally don’t pay much attention to Safari, but I just noticed a really neat new feature in Safari 5.1 under the Lion Developer Preview 4: a new downloads manager.

Apple’s new iOS 5 Weather app now delivers the local weather for your current location by default. Therefore you’ll always have a “here you are” weather report each time you open the app.

Firemint wowed us all when it updated Real Racing 2 to support 1080p video output via the iPad’s AV Adapter. It comes as no surprise to us, then, that when iOS 5 goes live later this year, this popular racing sim will be the first title to offer dual-screen gaming over AirPlay on your HDTV.

Samsung just launched its new Samsung Galaxy Tab advert, and in addition to blatantly mocking the iPad for its lack of Flash support, it also concludes by claiming the device to be better at web videos, multitasking, and gaming.

One of my biggest concerns about Apple distributing Mac OS X 10.7 Lion via the Mac App store has been resolved. One intrepid Lion beta tester has discovered a hidden secret inside of Lion’s installation application.

PDF Expert is a popular iOS app from Readdle that promises to be the ultimate solution to all your PDF needs. In addition to its excellent ability to let you read and annotate PDF documents, its latest update allows you to finalize documents on the go with support for signature fields.

Many customers eagerly awaiting the delivery of their Verizon iPad 2 are left disappointed when they check their order status to discover that their package is being re-routed on its way from China – all the way back to Apple. But why?

In honour of the final day of this year’s WWDC today, the iPhone Dev-Team may have a little treat in store for those of you have are running the first iOS 5 beta.

The integration of Twitter in the new iOS 5 firmware makes it easier than ever to tweet photos, webpages, YouTube videos and more directly from your iOS device… but did you know there’s also support for a number of other social networks within the Contacts app?

While the iTunes in the Cloud and iTunes Match features unveiled at WWDC this week have since been the center of attention for user in the U.S., users across the pond in the U.K. are still wondering when these features may be available to them. According to record label executives and music analysts, us Brits won’t get our hands on them until at least 2012.

Apple is shipping Mac OS X 10.7 Lion via the Mac App Store so how will you reinstall Lion without a DVD or USB stick? Here’s one way you can do it, but it might not be the best way.

A pair of iPhone 4s running an experimental science app are heading for the International Space Station next month, it was just announced at Apple’s WWDC.

This is a guest post by Adel Zakout, CEO and co-founder of OpenBuildings.com, a crowd-sourced architecture portal for building geeks.

The video of Steve Jobs presenting Apple’s plans to build a new “mothership” in Cupertino to the local council was absolutely hilarious! Not just because of the absurd questions the councillors asked but their obvious lack of professionalism, understanding of architecture and ridiculous fanboy-ism.

We love Apple too – but think that the planning process is really broken. The fact that Steve can clearly threaten to move his tax dollars elsewhere if the new campus doesn’t get approved shows that.
