With over 1 million applications being downloaded every day, it's no surprise that RIM would want to give its highly trafficked BlackBerry App World an overhaul. Although the design will look familiar, it's the tools that have been given a fresh reboot.

For example, BlackBerry App World now accepts Visa and Mastercard for app purchases, along with the original payment system on PayPal. This opens up a whole new, ahem, "world" for BlackBerry users who don't have a PayPal account to load up on apps.

But that isn't the only change in the BB App World. Hear about the other revisions after the jump.

Yesterday, I attended a BlackBerry showcase that featured some cool new apps that are coming to, or that are already up and running in the BlackBerry App World. I was pretty excited to learn about some fun, functional, and helpful apps for BlackBerry users, especially since there are currently over 40 million of you out there in the wild right now! Here, you'll find my five favorite apps that I think are worthy of a download.

• Seesmic — This free app acts as your Twitter hub, but there's more to come soon — Seesmic is integrating Facebook and LinkedIn feeds so you can get all of your social networking updates in one place. Its desktop and web apps are just as awesome for organization and productivity.
• Buzzd — This free app consolidates all your geo-location and social network updates from Foursquare, Gowalla, Twitter, Facebook, and more and tells you which places in your city are "buzzing" right now. Want to be where the action is? Then check up on Buzzd before you head out.

You can make payments and transfer money on your iPhone with the help of Square and your debit or credit card, but now with PayPal's new app, you don't even need that. Just by bumping your phones together, you can transfer money from one PayPal account to the other — no bank, check, computer, or credit card required.

The new PayPal app isn't just for your iPhone though — it works on your BlackBerry or Android device as well. To hear how it works, just read more

I use my cell as my primary number these days — I don't even have a land line anymore! At first, it was great because I never got any telemarketing calls, but over the past year that luxury has gone down the tubes (anyone else get those car warranty expiration messages all Summer? I don't even have a car!). Thankfully for you BlackBerry users, you can download a simple app called PrivacyStar to help you not only report telemarketing violations right from your call list but block unknown and unwanted calls too.

If you're on the National Do Not Call Registry but are still getting unknown numbers showing up on your caller ID, all you have to do is use the report feature to authorities; plus, PrivacyStar is the first app to provide a reverse call lookup feature that tells you who's calling you. Simple and easy to use, you can even manage your blocked calls list from the Internet. Best of all, PrivacyStar is free and is coming to other smartphones in 2010.

How neat is this?! The Edocrab BlackBerry app lets you scan barcodes on products while shopping so you can compare prices of items, get product info, access video clips and photos, and even buy the item directly from your phone. All you have to do is take a photo of the barcode with your BB's camera and Edocrab (which is barcode spelled backwards) will work its magic. And great news — it's totally free to download.
