PhoneView offers a huge list of features that cover all the major things your Phone can do.
1. You can simply use the Phone as a disk to quickly browse through files.
2. The ability to play music stored on the phone right in the system files. This goes the same for videos and podcasts.
3. Use PhoneView as a backup system, easily restoring all your data if something were to happen to your iPhone.
4. Organize contacts and export them from different locations. If you miss a person, you can simply add their data right from the menu instead of using the tedious touch screen controls on your phone.
5. Download the photos you've taken and add ones you want to share.
6. Manage your notes, as well as create new ones. This feature is great for when you want to quickly type a note to be used later on.
7. Use your phone as a portable harddrive, keeping files in the system for other uses. These files are not shown in the iPhone menu so nothing is obtrusive.
8. Export your SMS and MMS conversations to your computer quickly to a text editor or spreadsheet program.
9. Save voicemails to be played on your iPhone.
10. Play and save voice memos to your computer.
11. Browse through Safari bookmarks and history and open windows. You can also use a Search feature to find a website from your history.
