From what it looks like, the firmware 300.21.012 is pretty much stable for me except for a couple of calls resulting in my phone to hang for a couple of seconds. The camera quality on the 300.xx.xxx is pretty decent for me.
Looks like this one will have to wait till it hits my E71 (waiting for a working HelloOX actually 
)
