False Security Claims by Vendors

Galen Gruman on his Infoworld blog has noted recent - and not so recent - discoveries that some smart phone models lie to corporate servers.

Microsoft Exchange has a mechanism called Exchange ActiveSync which synchronizes data with mobile phones.

Owning versus controlling hardware

The Register recently wrote about how the latest firmware in Android phones tries to un-jailbreak them. Most smart phones contain built-in features to restrict the types of software they run. The built-in iPhone software restricts it to AT&T and to apps sold by Apple's own store. Blackberry and Android has similar restrictions."Jailbreaking" bypasses these protections to allow the phone's owner to install un-approved software. Android is fighting back in real time.

AT&T system logoSo the battle is on: who really controls a phone, or any other computer-based device? Most of us assume we control our personal computers. But phones are ambiguous. We want them to work reliably as phones, so we're willing to give up some control to the phone company. Back when US phones were an AT&T monopoly, we rented everything: from the network to the wiring to the indestructible desktop handsets.

On the other hand, we buy our cell phones. In AT&T's glory days, the Bell System never sold telephones, they only rented them. As owners, shouldn't we be able to choose the software to run, or the phone company to use?

Crypto bypass on the iPhone 3GS

Cousin Jon sent me this Wired link: how to bypass iPhone's 3GS encryption using jailbreaking tools. I haven't paid serious attention to the iPhone (AT&T hasn't had a strong signal in my town) but crypto bypass always gets my attention.

In fact, the weakness has nothing to do with protecting personal information on an iPhone. It's all about third parties: Apple, the cell provider, and possibly an employer who provides/manages the iPhone.

If you're not troubled by being limited to the iPhone Apps Store, then the threat's relatively small, especially compared to desktop systems. Moreover, I doubt we'll see real iPhone viruses as long as most people are happy with Apple's app restrictions.

Apple iPhone with GPS

According to the specs, my Palm Treo has a built-in GPS as part of the phone package. I was truly annoyed to find out that there's no way to make use of that capability.

Yes, GPS vendors should be scared by iPhone. But I expect they're going to get killed anyway by generic cell phones and Palm Treo-like devices. They generally have the mechanism built-in as part of the 911 call response mechanism.
