I've been waiting since the 9.6 upgrade for my iPhone to work again, everything was perfect on 9.5 for me but the making out going calls, upgraded to 9.6 and had that issue fixed, rebooted my phone the next day and everything went down hill, tried starting from scratch and still nothing. Phone reboots on it's own with yellowsn0w installed. I don't even get the option in cydia to update the app to 9.7 but from what I'm reading , it doesn't sound so good to do
