In conjunction with BlackBerry App World 2.0's emergence from beta today, RIM has announced that developers will now be able to charge 99 cents or $1.99 for their wares. Doesn't sound like news, right? Well, it is, because the company had previously set a minimum of $2.99, an attempt to keep... well, for lack of a better term, crap out of its official marketplace. What we assume RIM has since discovered is that lots of devs with great apps want to go for a volume play, not a margin one -- it's a strategy that has worked for plenty of folks in the iPhone App Store -- and they're looking at this as an easy, quick way to get more people interested in porting the good stuff to BlackBerry 6. Canabalt on the Torch, perhaps? Other notable improvements in 2.0 include non-PayPal credit card payments, new app browsing options, and a new BlackBerry ID that'll let folks move both free and paid apps between devices when they upgrade -- in other words, it's a worthwhile download.
