I've AGAIN started having multiple "copies" of the SINGLE text message being sent to the recipient (
) This is not only annoying to the recipient but uses my allotted text messaging (250 in my case) 2 to 5 times faster than it should 
I think I "correct" it by: powering down, battery pull, SIM reseating, SD card reseating, bla bla bla... I am in full RED 4G coverage
per the map, have wifi and Bluetooth off, am using Handcent as my SMS (since day 1), and have no newly downloaded apps. This happens on & off Verizon's network (tested to my wife's Verizon iPhone 4 when it happened this AM and she got multiples)
I emailed Verizon support and will post their "solution". It would also be nice if Verizon would release a Thunderbolt version of MyVerizon for us "stock" owners, especially if this problem doesn't get resolved permanently
