If you have a cell phone or PDA, it's sometimes inconvenient to have to synch to your PC in order to transfer files from your PC to your PDA. There are also problems if you're not in the office. You may want to move a file to your PDA while you're at a conference, but, without your cable, you're out of luck.
So, what the solution? Obviously, it's Beam-it-up-Scotty, or I wouldn't be asking the question.
It's simple to use. Go to the site and upload the file. Then enter your phone number. In a few moments, you'll get a text message with a link to download the file onto your phone.
The first time you try it, you'll be sent an e-mail to confirm. Once you've done that, the text message will display, and you won't need to confirm again.
I wouldn't expect to use it often, but it's certainly a nice alternative if you left your cable at home.
