Dropbox, the über-slick cloud storage and backup app, now has an iPhone version. You can use the iPhone app to get to your Dropbox on the go, sync media files from your phone to your Dropbox, and share links. You'll need a free Dropbox account - which comes with 2 gigs of storage space - to use the iPhone app, but you can sign up directly from your iPhone.

The iPhone app works with Dropbox's photo gallery feature, so it's easy to upload and view photos on the go. You can also download any of your stored files that you can view on an iPhone, which strikes me as pretty darn brilliant: now, instead of just using Dropbox to back up your computer, you can use it to back up all the media on your phone, too.

If you're away from a computer and your iPhone's music and photos get wiped, they'll still be safely waiting for you in your Dropbox.

Update: Although you can obviously store music (and anything else) on your Dropbox account, there's not actually a way to sync music to your iPhone via Dropbox. Oops. Photos and videos definitely work, though.

If you have the ability to install software on your work computer, by far the easiest way to move files back and forth between your home and work computer would be a file synchronizing product like DropBox. But if you don't, what's the best way to move a relatively large file between two remote computers? For small files, email is usually the answer, and for users of Gmail that expands to files of up to 25 MB in size. But with what can often be a big catch: Gmail won't allow you to transfer executable files, even if they are inside a zip archive.

However, if you're simply wanting to move a file between computers, you can exploit the fact that Gmail doesn't actually scan a file to see if it is an executable until you actually try to send the email containing the file. This means that you are free to attach any file up to 25 MB in size to an email in Gmail, as long as you don't send it. You can then log into your Gmail on another computer, and download the attached file, without ever running into the executable file restriction.

Of course, the other easy way around Gmail's limitation is to change the file extension of the file you are sending. If you have an executable file inside a Zip archive, and you change the archive's file extension from .zip to .zzz, for example, Gmail doesn't know what a .zzz file is and does not scan it. Voila, you can now easily send executable files through Gmail.

Microsoft has Live Sync, Apple has MobileMe, and Canonical is now beta testing their own user data synchronization service called UbuntuOne.

The service works as you'd expect - set up your sync, access files anywhere, share your online items with anyone you choose. Currently lists two service levels - 2GB of storage is available free of charge, while an upgrade to 10GB will set you back $10 per month.

The service will likely provide a decent revenue stream for Canonical. As for me, I'll be sticking with DropBox on my Linux Mint laptop.

Not only does the DropBox pro account offer five times as much storage (50GB), there's also a $20 discount for paying annually - dropping the monthly fee to just over $8. On top of that, I can use DropBox to sync with my Windows desktop as well.

Perhaps the developers will amp things up a bit before UbuntuOne is finally released.

Way back in January I wrote about my corporate-sanctioned machine, complete with a few pieces of bloatware (sorry kids!). I appreciate the awesome suggestions, although since I need this thing for work purposes, I'm opting to go light and lean whenever possible to begin with. Yes, I realize Microsoft Office is the antithesis of "light and lean" but the suite is required to stay on the machine. For everything else, I want a small footprint.

Case in point: I needed a screenshot app. I chose MWSnap because it was small and unobtrusive, and didn't require an installation. It isn't perfect, but it does the job and I remember using it years ago. Unfortunately, my next series of application downloads wouldn't be so lean.

Note that a collection of applications says a lot about the primary user and what they will be doing day-to-day. A few months ago I ran a Twitter straw poll for TUAW and found a large portion of followers were web designers and developers, judging from the software they were using at that time. My use case is simple: I'm using this machine to test software for DownloadSquad, learn some programming, and take basic screenshots and possibly screen video. So far, I'm almost where I want to be with the base set of applications. To see what I've installed so far, keep reading.

Dropbox has gone public, opening it's file sharing and backup services to the public. The cross-platform tool makes it easy for users of multiple computers and operating systems to keep their files safely backed up and in sync.

Brad first posted about Dropbox in March, and the development team has been hard at work ever since.

Once you've uploaded a file, the software is smart enough to upload only the changes. For anyone who has an ISP with a ridiculous upload cap (30k/s for me) it's a welcome feature, since it means I won't be uploading a 75 megabyte PSD over and over. It also makes sharing work with my Mac-using partner a snap.

The web interface - "Now with lots of Ajax!" according to Dropbox - has seen a number of improvements. It handles multiple uploads nicely, and makes accessing and storing files a breeze even when you're not using the desktop client.

You can view a screencast of the service, or take the old-fashioned tour if you'd prefer.

Dropbox is feature packed, gives you 2 gigabytes of free, online storage, and is definitely one of the better services available.

While there's no shortage of online file storage and synchronization services these days, Dropbox has to be one of the simplest solutions we've seen. Here's how it works: You install the Dropbox client on your desktop, and then every time you drag a file into your My Dropbox folder it's automatically uploaded to the web service. You can then view your file, share the link with others, or keep it synchronized with multiple computers. There's even a version tracking history. If you edit or delete a file, My Dropbox will let you undelete it or will show you previous versions.

Beta testers can store up to 5GB online, and there's no file size limit. Once it launches, Dropbox will offer free and premium services, with free account holders getting somewhere around 1GB of storage space while paid subscribers will be able to get more space. Users who are in on the beta will get to keep their larger accounts once Dropbox exits beta.

There are Mac and Windows clients available right now, with a Linux version coming... eventually. You can sign up for a beta invitation at the Dropbox home page.
