I see a few posts on here regarding this combination. Samsung Kies suggested firmware upgrade so I upgraded to ICS, Android 4 and ever since then I've had endless problems with the phone and B&Me. In the end I reverted the phone back to Gingerbread, Android 2.3.6 and the phone is now working as it used to with B&Me. So my advice is, if your S2 is on 2.36, DO NOT upgrade the firmware if Kies suggests it. 2.3.6 seems to work fine with B&Me, 4.x does not.
