Cortado Connect and Box.net are giving users of BlackBerry smartphones 1 GB of free online storage for pictures, files, music, whatever. If you want more storage, however, you'll have to cough up some dough. It's sort of like a mini-FTP for your phone. Check it out.

Box.net offers the free online storage to just about anyone. Simply sign up and away you go. For 1 GB of storage, there is no charge. For 5 GB, you can pay $8 per month, and for 15 GB it is $20 per month. The free version caps file sizes at 10 MB, but the two for-pay options don't have caps on file size uploads.

Here's how it works. The Cortado Connect software is an Internet storage solution optimized for BlackBerry users with BlackBerry Internet Service. With the software, BlackBerry users can manage their local and online storage, with the ability to transfer files between them directly from their handset. Users can store music, video, and documents to their hearts content (as long as it's 1 GB worth of content).

The steps to sign up are pretty simple. Go to Box.net and sign up for a free account. Download and install the Cortado client on your BlackBerry. Use Cortado Connect to access your Box.net account, and begin managing your files. Once you've done that, you can set up shared folders with colleagues or friends to swap files. This can make it truly useful when it is too difficult to send files from phone to phone via e-mail or MMS.

Cortado also makes similar clients for Windows Mobile, Palm OS, and Symbian devices. If the storage capacities offered from Box.net aren't enough for you, it also offers enterprise support and services.
