An increasing number of lawyers and firms are adopting iPhones - a trend evidenced by the increasing interest in the devices at TECHSHOW. But before you rush off to find an app for that you might want to pause to consider what you're going to use that iPhone for.

In recent weeks security researchers have discovered or announced a number of serious security flaws in the iPhone. One of those flaws, the SMS bug that affects a number of mobile devices including the iPhone, has apparently been patched in the most recent version of the operating system. However a serious vulnerability that could allow someone to bypass the iPhone's encryption and access the data from the phone (which might include contact information, e-mails, even documents in some circumstances) is apparently still an open issue.

For more details on this issue read John Simek's article at:

Whatever mobile device you choose you need to exercise caution about what data, including e-mails and attachments, you allow on the device.  Losing your phone is bad enough. Losing your client's confidential work product (and the other things you might lose as a result) is even worse.
