i have had att verizon and am on sprint now...i am still with sprint because of the simply everything plan but my contract still ends in august so once all these new phones drop i can make a better decision...but like others were saying the speed on verizon is great and eventually most carriers will get the same phones sooner or later...sprint just got the curve although other carriers have had it for a while but it's here now...and suppossedly verizon is going to get the thunder exclusively so you can wait for that if you want or get the bold when that does drop...like everyone else said as well it's based on personal opinion...i have better coverage here in hawaii with sprint then i did with verizon and att...but that's just here
