Got my Aqua Fish today put my sdCard in and restored latest Jolla TOH backup and it worked without a glitch.
Dev mode, SSH enabled and Warehouse installation went incredible fast if i compare to TOH.

First impression: everything works a lot faster even with 5-6 apps open at the same time.

Still have to test camera and radio.

Unfortunately only downside right now is a major one: cant work out 4G here in Finland (Sonera) although Intex and Carrier are supporting 1500Mhz.
