The first couple of days I got my Epic I was having this exact problem with the stock sms and handcent, people were receiving 3 of the same txts for me and most of them were failing to send the first few tries but apparently my resends were the reason for the duplicates, This week however none of my txts are failing, they're actually sending faster, the only time they possibly fail is if Im tryna send a txt out then one comes in
