Can anyone assist me in locating passwords on the iPhone? I see only a basic phone lock when your phone is turned on. I'm not seeing any passwords for locking specific areas of my phone. Why Apple would include features like visual voicemail which doesn't require any dialing or logging into your voicemail, YET no way to lock it is beyond me. It would be nice if I could also locate a password lock for things like my contact list, which contains over 100 friends at this point. Anyone with any info would be appreciated. Also, if there are, as I assume, no locks on this phone, are there any other options to help me? I'm so disappointed in this phone, as it seems there are many features lacking. Especially the simplest features. I'm very frustrated. Thanks.
