Just bought my 3rd Nokia .. 3rd time is a charm right? Bought the 920 when it came out. The pentaband from Canada, sold it .. regretted selling it and bought another. The second one didn't work. They must have messed something up and it couldn't read my sim card. Today I bought another .. this time a 1020 unlocked AT&T from Amazon. This one comes with the camera grip. I didn't know before buying that the camera grip is also sort of an emergency charger .. that's nice, or am I wrong?? My question is actually a general question about the camera grip. Does a person carry it apart from the phone ?? or do you leave it on at all times .. I don't suppose it fits over a case, right??? I don't know if I can stand waiting almost a week to get my new phone. Should have chosen overnight shipping....
