I have been running Hyperdrive RSL8 KK and love it, just like I did the RSL7 but for some weird reasons Hyperdrive starting killing my battery and I've got the Zerolemon 10,000 Mah battery. I tried everything and nothing worked...I mean everything. I even did a complete wipe and restored a good clean backup that I made right after I installed it and it was working perfect.

Nevermind about the Wifi hotspot...finally got it working.

Also, has Hyperdrive come out with a newer version than 8?
