An Update on the Smartphone Antenna Wars

Over the past few weeks we’ve reported on the iPhone 4’s infamous antenna reception issues and Apple’s solution to provide free bumpers. We’ve also covered Apple’s assertion that reception troubles are as prevalent among other smartphones as they are among iPhone 4 users. Specifically, we discussed how Apple used video evidence to single out RIM, HTC, Samsung, and Motorola for supposedly manufacturing phones equally as flawed as the iPhone 4, and we also detailed those companies’ respective responses. Well, apparently Apple’s propaganda war against its competitors is now over, at least as far as Apple is concerned. Apple removed the incriminating videos from its website. Let’s hope everyone involved can now get back to making great smartphones.

New Apple Security Flaw

Yesterday we posted a blog that provides the pros and cons of jailbreaking your iPhone 4. We also detailed how to jailbreak the phone through the website jailbreakme.com. The website utilizes a security flaw that allows it to download a PDF file directly onto the iPhone. Code inside the PDF file is then used to jailbreak the phone. While jailbreakme.com exploits this for a completely benign purpose, hackers may use the same security oversight to disable or otherwise compromise the iPhone or any other Apple device. Apple has yet to release a statement regarding the security flaw, nor has it provided a security patch.

It should be noted that the PDF security problem can only harm your phone if you visit a malicious website. Such websites can automatically download a simple PDF document to your iPhone and then release a virus imbedded within the file. The virus can do anything from stealing your address book to remotely viewing everything you do. This can happen even on non-jailbroken Apple devices.

Fortunately, there is a fairly simple way to overcome this security flaw for the time being if you jailbreak your phone first. We highly recommend doing the jailbreak through jailbreakme.com. You can then download an app called PDF Loading Warner, available through the unofficial Cydia store, which alerts you whenever a website attempts an unauthorized download. The reason the phone must be jailbroken first is because PDF Loading Warner is an unofficial app, which means it’s not available through the iTunes App Store. While this doesn’t completely resolve the security issue, you will at least see a warning anytime a PDF file attempts to download. This warning lets you choose whether to allow or abort the download.

Jailbreaking and Unlocking Your iPhone

A recent ruling handed down from the U.S. Copyright Office now legalizes the jailbreaking and unlocking of cell phones in the U.S. So what are the advantages and disadvantages of jailbreaking? This blog entry answers those questions with attention specifically directed toward the iPhone 4, which is the smartphone most affected by this ruling.

Let’s begin with the positives. Jailbreaking your phone allows you to download apps from anywhere, not just the iTunes App Store. This is important because Apple refuses to authorize certain kinds of apps. Specifically, there are no apps in the official App Store that let you customize the home screen or turn your iPhone into a Wi-Fi hotspot for your laptop. However, such apps do exist elsewhere on the internet for jailbroken phones. Many suspect that jailbreaking may even allow for the development of apps that let you video chat over 3G networks; currently this feature is only available over Wi-Fi. Jailbreaking the phone will let you visit non-Apple websites to download these and other apps.

Unlocking a smartphone is also desirable for one important reason: it allows you to use your phone over any GSM network. The only GSM networks in the United States are AT&T and T-Mobile, which is bad news for those who want to unlock their phone and take it to Verizon or Sprint. However, the ability to legally unlock your phone is great news for those wanting to take the phone to T-Mobile.

So what’s the downside of jailbreaking your phone? As Apple was quick to point out following the government ruling, jailbreaking voids your warranty with Apple. This means if the phone turns into a brick—tech lingo that essentially means the phone is broken—Apple likely won’t fix it. In other words, jailbreaking could leave you with an expensive iPhone that can’t do anything. Furthermore, all iTunes apps are pre-approved for download by Apple while apps downloaded from other websites are often less likely to have been thoroughly tested and are more likely to contain harmful viruses.

Despite the potential harmful effects, many readers will still choose to jailbreak and unlock their phones. And remember, doing so is not illegal, though it should only be done with caution. So how exactly does one jailbreak an iPhone or other Apple device? The easiest way is to visit www.jailbreakme.com directly on the device you want to jailbreak. A prompt will pull up asking permission to download. You can then unlock the phone through a different program once it has been jailbroken. At this time we don’t know of any unlocking programs that are safe and reliable, but we will keep our readers updated on any good ones that we find.
