RIM Seems to have let the cat of the bag on this one. PhoneNews found out that Virgin Mobile USA is now listed on the software download section of BlackBerry.com, which shows support for the Curve 8530. What PN failed to mention was the OS for the 8530 is new! This will be Virgin Mobile USA's first BlackBerry device. Virgin Mobile appears to be targeting their competitor, Boost Mobile, which recently released their first pre-paid BlackBerry.
It is not too odd for a carrier to get the OS software support online before they release the device (remember China Mobile with the Curve 8910?). Either way, this is good news for those who already have the Curve 8530, as OS 188.8.131.521 has been made official, just remember to delete the vendor.xml file to install.
