iPhone & android OS, device driver, & app security is a joke. They are virtually unsecurable.
My company and customers use blacberrys, they are not perfect but are an odred of magnitude more secure that the iPhone, Android.
We are looking for AV protection, firewalling, security sandboxing for apps, devive drivers, OS for real no-kidding security on Blacberry.
When will you support those capabilities for Blackberry ?
McAfee Consumer products don't cover phones at all, sorry.
I suggest Googling for them, here's one article: http://askbobrankin.com/antivirus_for_smartphones.html
There is some mobile security on the Enterprise side but that involves bulk licensing only, for companies.
