Help Sending texts on restart

[jammychap]

Hi i've been having a problem with my Sensation XE, if I restart my phone it sends the last few texts again then i get some replys like you told me that yesterday etc, anyone know why it is doing this? is it app related.

I installed the latest 3.33.401.106 software yesterday, still doing it

sense v. 3.6
android ver. 4.0.3

Don't know if it makes any difference but i'm on Orange network.
