Mobile social networking service JuiceCaster has snagged its biggest carrier deal yet with T-Mobile USA.

With JuiceCaster, it takes just one click to share pictures and videos right from your phone to more than 20 social networking and blogging sites including MySpace, Facebook and Twitter, Juice Wireless says of its product. The new JuiceCaster 6.0 adds the ability to post and watch real-time video status updates on a mobile device.

T-Mobile, which joins Alltel, US Celluar and Cricket Wireless as US carriers offering JuiceCaster, will make the software available on a dozen of its best-selling phones for $2.99 a month for unlimited use.

The service should be available to T-Mobile customers early next month.
