Threaded txt's look to be a little whacky in 5.0.0.419. Prior the thread would contain everything sent and received. Now there is one thread for sent and another thread for received
I've got two 9530's that I loaded .419 onto yesterday, they both are doing this split thread thing. Can others take a look and post results, maybe it's a config on my end?
try going into Options > SMS Text and change your text format. I went from Bubbles to Stripes....or vice versa...lol. Doing that took the lines out of my SMS strings.
