I have never heard of this service before until Wojitas mentioned it to me. It looks like a new BlackBerry application that makes a backup of your contacts on their servers and lets you share content with services like YouTube, Facebook, and more.
They have a free and premium account option but I cannot really recommend the premium account except for one feature. It lets you restore all of your contacts back to your BlackBerry more than once a year. I guess this is targeted at Europe due to the prices only being in Euros but it is definitely worth a look if you want a free solution for backups… Though you could always use Google Sync…
Personally I think that if you are willing to pay you would be better served with a hosted BES solution or SmrtGuard at the very least.
Check it out at www.pleex.com and let me know what you think. You need to register on their site from your PC/Mac first before you can download the app.

I use UpVise for the same thing, and suggest people also try upvise.com

…downloaded UpVise and dont see option to upload files (mp3, videos, pictures etc.) via app. Also free account has some limitations.

True you can’t upload mp3s, but you can backup your Contacts, and then access them via the web. I also like that when I make notes in UpVise, they are also available online for me to manage

I recently came to the conclusion that there is no really good online contact manger, so I started thinking about what it would look like and this is what I came up with…
