Yes, another custom Amazon Kindle Fire ROM was released. It is HellFire Kindle CM7 ROM. And based on Android 2.3.7 Gingerbread which I prefer. Android 4.0 Ice Cream Sandwich on Kindle Fire is still not perfect yet. And will be better when ICS kernel is fixed. Until then, I am sticking to Gingerbread ROM like CM7 on my Kindle Fire. How about you?
