So there's a significant difference between I8150 and I8150B? I bought mine on Brazil and couldn't update it to 2.3.6 version via Kies Air (it doesn't show any option that might be it).
That's my first android phone and like the presentation video said, i'm a freaking noob (but very interested in learn). In the settings i couldn't find any information about the firmware. I found the Android Version (2.3.5), Baseband Version (I850BVJKJ5) and the Kernel Version (22.214.171.124-perf-I8150BVJKJ5-CL680217se.infra@SEP055 #3(i believe this is about the linux kernel or something).
