Wohooo, you are great. I could follow your steps.I have only 2 problems:a) I have no supported device to upgrade the Fit to 1.49 - will have to ask around in office if somebody has a supported Galaxy. Anyway, it would be great if we could manage to get the upgrading function working so we are independent of any special device requirements... not sure, what's missing here, because as somebody earlier mentioned: when pairing it with 1.25 the first time, it downloads a huge firmware update and pushes it to the Fit who afterwards reboots... but either it didn't work or it is not 1.49b) Have the same problem with the S-Health lite - it can be started, but it is not able to logon to a Samsung account or sync with the FitAnyway, this is a huge progress so far. I bought my Fit today. It was released yesterday and only one single store had it on stock - when I found your thread, I immediately rushed to the storeThank you so much for all the details you figured out so far.
