What apps do you need it for? I need mine for torrenting with iTransmission and I've found the workaround by changing the .plist file. InfinityTask works too.
Warning: some Cydia articles state AirBlue Sharing does support iOS8. It's in no way the case - don't bother.
I can't link to them as some of them directly link cracks. Nevertheless, googling for for example "How to Install AirBlue Sharing iOS 8 iOS 8.1 For free" shows some of these articles.
I really hope the dev updates it some time. It's so useful in the world of every other device / OS supporting full Bluetooth, just not Apple's pityful, crippled implementation.
add to the list, it works: Ayeris, audio recorder, browser changer, colorbadges, disk pie, GifViewer, Live Battery Indicator, NetworkList, NoUninstall, NoVibratedWakeup, NoVoiceMail, voicechanger
