Currently looking at 2 SIM phones: HTC Desire V ($275) and Samsung Galaxy S Duos ($325). Specs appear to be more or less similar on both. From my research, the HTC Desire V appears to be dual standby. However, I can't figure out if the Galaxy S Duos is also dual standby or if it's dual active. If it's dual active, I think I'd be willing to shell the extra $50 for the Galaxy. If not, I'd just stick to the Desire.
Another phone I'm considering is the Sony Xperia Tipo Dual ($145). However, I'm seeing conflicting statements on whether it supports dual standby or not. Does anyone here know? Thanks!
