With the proliferation of smartphones generated in part because they do so much and they are become less expensive to buy and own, the idea of security is becoming more important. The Android platform, for instance, has had some relatively high-profile malware distributed on it. The malware will surreptitiously send texts and calls to premium services costing the owner of the phone money (and racking up a chunk of change for the malware author).

This article at InfoWorld talks about a couple of different malware examples. One of these was even present in software available at the Android Marketplace. I tried to find recent articles on iPhone malware but I didn’t see much. This article specifically mentions “jailbreaking” as making your iPhone more vulnerable to malware. This makes sense as doing so allows you to install software from sources other than the iPhone App Store. It also allows you access to your phone that Apple didn’t intend you to have. This article from a year ago talks about a researcher who created a proof-of-concept app to gather information from your phone. He said that it would be possible to create an app that would look like something you wanted but have this secret ability running in the background. Given how Apple has to filter thousands of app submissions each week to its store, it’s conceivable that malware could get through.

The takeaway from this is to be careful. Anti-malware software is available for your phone like it is for your computer. Only download software from trusted sites and be sure to read reviews before installing (I know I’ve not installed many software titles just because the reviews said they sucked or didn’t act as advertised). Be extra careful if you choose to “jailbreak” your iPhone or gain root access to your Android phone. If you allow your children to play with your phone, be sure to approve any app they wish to install prior to its installation.

I’ve not discussed the current mobile offering from Microsoft. Regardless of its merits, the iPhone and Android represent the lion’s share of smartphones today.
