Norton should consider developing an iPhone security package that both mirrors and interfaces with Identity Protection--i.e., secure login ID's and passwords for web access from the iPhone. Thus, the user only has one set of security tools to manage, whether using their WIndows PC or their iPhone. Along those lines, Internet Security (firewall, e-mail scanner, anti-malware) protection for the iPhone would be a welcome addition.
I'm pleased with Norton 360. As a new iPhone user I'd like to have the same services available on my iPhone, which are integrated with my Windows PC so I don't have to worry about managing two sets of Identity Protection. I've looked at a few of the password security apps available and all I can say is you obviously get what you pay for.
Lastly, an integrated (with 360) data vault function--both Windows PC and iPhone--would be great. Having a secure place to store credit card numbers, passport info, etc. Would be fantastic.
