As the title suggests, what are the big differences between these? The AT&T variant seems to be riddled with bugs, judging by these forums and reviews. Are these mainly due to lack of firmware updates? Or are there other issues going on? Are there any drawbacks or issues using the MS unlocked variant on AT&T's network (besides footing the full cost of the phone up front)? Any loss of features?
Does the unlocked variant seem more stable, for anyone who has perhaps used both?
