I'm not 100% on why it was getting hot, I noticed too that the lockscreen would hang up, a soft reset puts it back how its supposed to be though and the account settings was definitely a draw back sorry
I'll mess with it and see exactly what' was going on with it.
I'll post a new 21169 based rom here in a bit, its not looking bad, everything seems to be running pretty smooth so if it stays that way I'll put it up for ya to play with.
