Yeah, it's quiet stable, I haven't found no bugs yet (using for 3 days). But there are now google services at all, 3g and ADSL settings are added (no opportunity to test), service "DC Store" (no idea about what is it), chinese app for youtube (so called Tudou, workable!). Camera, wifi works good. I think, that battery usage was improved. IMHO, a bit faster firmware.
