i went back to the store to do a refund (LOVE the vibrant but honestly cannot handle with all my freezing, slowlyness, black screens, etc... anymore). the guy there told me there is no better phone for me and he can refund me but don't think it's a good decision for me (i know the guy so i don't think about salesman-customer bulls**ts) and here on some thread i read that after getting a new device some of the problem users had, have been gone. so i think the best way for me to make this decision is to make sure the new unit the store can give me is really newer than mine and not the same. how can i do that? many many thanks!
