Aside from SMS Spam, looks like smartphone and PDA phone users now have "Smishing" to deal with:

Some cell phone users have started receiving SMS messages along these lines: "We're confirming you've signed up for our dating service. You will be charged $2/day unless you cancel your order: [sample URL]"...

This phenomena, which we at McAfee Avert Labs are dubbing "SMiShing" (phishing via SMS), is yet another indicator that cell phones and mobile devices are becoming increasingly used by perpetrators of malware, viruses and scams.

Let's practice common sense people! It's a wild wireless world out there. Thanks to the VoIP Weblog for the heads-up.
