Jailbreaking How-To: Enable Multitasking (and More) On iPhone 3G or iPod touch 2G

So, you want to enable multitasking and other iOS 4 features on your iPhone 3G or iPod touch 2G? Well then let’s get to it!

You’ll need an iPhone 3G or iPod touch 2nd-gen, as well as the redsn0w jailbreak, which you can download from here. Now you’re set to do the real work, but first a disclaimer: the procedure is rather simple, but be warned that you could easily brick your device if you’re not careful. Also, jailbreaking will void your warranty, so be smart and restore your device with iTunes before you take it down to the Genius Bar.

Got it? Great.

If your device is still running on iOS 3.x, you’ll need to upgrade to 4.0 before you proceed. Just go into iTunes, click on your device in the sidebar, and check for updates.

Taking the Pen to the iPad

The iPad has been successful by anyone’s method of reckoning. Apple has done what it does best — create a compelling device that is useful for many things that people like to do. Many iPad users tell me, and I agree, that it is more useful than they thought it would be. But there is one more use that many users would like to see. It is only natural to take a pen to a slate device, but it doesn’t work very well with the current technology. That should be set to improve when a concept by Ten One Design that adds pressure sensitivity to the iPad gets implemented. Many concepts never see the light of day, but Ten One is releasing this one to developers.Read more...

Apple Says Signal Strength is Just a Software Issue, But is It?

Apple heralds the arrival of the iPhone 4 as the most successful product launch ever, but since the device first went on sale, reviews across the world have remarked on issues of signal quality. From notions of holding your phone incorrectly to simply displaying an inaccurate representation of signal strength, the issue has become prominently associated with the popular phone and could affect its sales. Today, Apple finally released a response addressing the concerns.

Apple Admits to iPhone 4 Antenna Problems... Sort of

Breaking news! Apple admits to iPhone 4 antenna problems! Well, sort of. According to a press release issued by the company this morning, the iPhone 4 doesn't have a hardware design flaw - it has a software bug.

"We were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong," says Apple. "Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength."

Will Mobile Web Apps Eventually Replace Native Apps?

Last week I had the chance to attend Qualcomm's Uplinq 2010 conference in San Diego where I was able to sit it on several interesting discussions about mobile technology and its future. One of the sessions I was particularly interested in was a chat about the tools being created to improve web development optimized for mobile devices. Qualcomm engineer Bijan Amirzada showed off some interesting new capabilities within mobile Web browsers, but one assertion he made has since been stuck in my mind: will Web-based apps eventually dethrone native applications on mobile devices?

The Biocep R Project Brings Open Science to the Cloud

The explosion of "big data" has prompted many people to ask the question "How will we store all this data?" And while cloud computing offers the promise of infinite scalability for storage, the Biocep R Project hopes to address two related questions associated with the growth of big data: "How will we analyze all this data?" and, more importantly, "How can we analyze it virtually?"

As the name suggests, the Biocep R Project is built on R, a free software environment for statistical computing and graphics that's described as "the lingua franca of data analysis." But despite its increasing use, R has several shortcomings in terms of standardization, usability and collaboration.

An ISP Offers A Cloud for India - More Like AOL, Less Like the Open Web

We are winding down the long holiday weekend here in the United States but in the southern hemisphere, the news cycle is in full gear.

And so the story about a new cloud service in India caught our attention as it demonstrates how the cloud is reaching millions of people who have no access to a computer nor a credit card. It also is illustrative of how the cloud will be more for a global community of mobile users who access a service that is more like AOL than the open Web.
