Use your iPhone for file storage
PhoneView (formerly known as iPhoneDrive) allows you to turn your iPhone into a storage and syncing device. It's the perfect desktop companion for iPhone and iPod Touch owners that want to get the most out of their mobile device.
It doesn't stop at storage and syncing data however. PhoneView can be used to access and backup iTunes, voice memos, voicemail, photos, notes, SMS/MMS, contacts, and call history data. You can transfer data from your Mac to your iPhone in the form of text, Word or PDF files into iPhone notes. The drag and drop interface makes it easy and fast to transfer files both ways.
The interface and ease of use of PhoneView is superb. However, many users have reported problems of it not working either when their iPhone firmware has been updated or with 3G iPhones. Subsequent updates have solved these problems, however. In addition, there are problems with iOS 4. For example, Notes add/edit/delete, Call Log delete, Message delete, and Camera Roll delete are not available for iOS 4 devices.
Overall, PhoneView is a handy and efficient iPhone management application that will help you get more out of your iPhone.
