DataCase is one of a number of apps designed to bring file system capabilities to the iPhone. iPod users have for some time been used to using the storage space on their device for files other than music, and Veiosoft have stepped up to bring this capability to the best iPod of them all.

From the screenshots, it's clear to see that a lot of time and effort has gone in to making the app feel polished and unique; this wasn't put together overnight. Security is handled in a way many mobile users will be familiar with from using bluetooth; the app pops up an Allow/Deny dialog when something, somewhere tries to read a file or folder on the phone. This means no need for logging in iwth a user ID and password, but it's a shame that I can't simply leave DataCase running in my pocket and get full access on my computer without the need for going back to the app to allow ocnnections. Fortunately it does remember your authorizations, and won't pester you about allowing access to the same directory structure after the initial access. There is also the option of allowing authorization-free access to selected areas of your storage if you don't care who or what can see what you've stashed away in there.
Connecting to the iPhone can be achieved with AFP, FTP and HTTP protocols. What does that mean? Well, it depends what your favourite operating system is...
Mac OS X
If you have a Mac, this is the file store app you've been looking for. AFP (Apple Filing Protocol), coupled with the Bonjour service discovery protocol, means all you need to do is run the DataCase app on your iPhone and it will automatically show up as a file system in the Finder sidebar on any Macs connected to the same local network. You can then use the file system in the same way as you would any other; you can read, edit, drag and drop, delete, and manage folders. Any changes you make are made directly to the iPhone. This is how mobile storage should be, and hats off to the developers for the effort involved; I hear they implemented the whole protocol stack in-house which is a hefty amount of work. Now if only the same level of integration and slickness could be found on...
Windows
On the downside, things aren't so easy on Windows. AFP is not supported directly by Windows, and I haven't found any third party software to add support (but if you know better then let me know via the comments!). This leaves Windows users with two options, HTTP and FTP. HTTP lets you view and copy files from the iPhone, but no modifications can be made. FTP goes one step further and lets you create, delete, and drag and drop files and folders. However the problem comes when

you try to edit a file; the only way to achieve this is to copy the file to a local file system on your Windows machine, edit it, and then remember to copy it back afterwards to update the iPhone. It's a far cry from the slick Mac desktop integration. However, I was told by a Veiosoft developer that they are working on adding DAV protocol support in an update in the next month or two, and on the horizon is SMB support, which means fully-fledged network drive support for both Windows and Linux. This will be a great achievement if they manage it and could make DataCase unnassailable as the iPhone file store app of choice.
So is it worth £3.99? If you have a Mac, it's a no-brainer; zero-config, full file access and a good UI. Stuck with Windows? Then you have a choice between buying this now and making do with FTP access while waiting for SMB support to come, or taking a look at the competition (watch out for a review of Files coming soon). My advice? Veiosoft have produced a very professional application, carried out a public beta test to ensure quality, and their customer support is polite, responsive and detailed. They seem very committed to making DataCase a success and continuing to refine the program in the future. This is where I'd put my money.
Summary: Good app, destined to be great in the future with further protocol support. Best of breed file system access for the iPhone.
