F-Secure are a fairly reputable company. And it's not as if they are trying to sell a virus checker in this instance.

Another report here. Hopefully Apple will fix these exploits real soon now. Smart phones are going to be the future target of the script kiddies, and it's only a matter of time before there is a serious infestation. Just think of the fun a spammer could have - not to mention the resultant phone bills!
