The only webOS-related news we really want to hear out of HP’s camp is here’s when the Pre 3 and TouchPad are launching, but we suppose last week’s quiet App Catalog update is also welcome news. The new version of HP’s webOS App Catalog features several changes, some more important than others. The first thing users might notice after updating is the presence of HP’s logo on the Catalog icon — an inevitable branding change that should probably have happened quite some time ago. More important, however, are two key new additions: promo code support, which will allow users to download paid apps for free with a code obtained from a developer, and carrier billing support, which will allow paid apps to be billed along with monthly cell phone service charges. The new version of the App Catalog is also said to be a bit more responsive, and it requires webOS 2.0 or higher to run.
