Amazon stops blocking rival e-reading apps on Kindle Fire

People just keep digging up interesting little tidbits in the latest Fire firmware update. It may have killed the ability to root but, it did grant access to the Android Market website (even if you still can't install apps from it). Now some users have noticed that competing e-reader apps are available through the Amazon App Store. The rival readers were allowed into the shop, but hidden from view on the Fire. Now that's changed and Amazon's tablet, even with out Super User, is getting just a tiny bit more consumer-friendly.
