Bugs are to be expected in brand-new apps and platforms -- particularly when they're clearly marked with a "beta" sign -- but it starts to get a little harrier when there's money involved. One of the early crowd favorites in Nokia's Ovi Store for Maemo appears to be the game Angry Birds, which is available with a €3 level pack -- problem is, plenty of folks have discovered a way around actually paying the cash, which becomes a big problem for the developer very, very quickly. The level pack has since been removed, probably the best move until Nokia can figure out what's going on here and issue a patch. In the meantime, looks like it's back to the ol' repositories.
