well i have my sense since debut date and have experienced every issue the op has, i have hard rebooted bringing phone back to factory settings twice, constantly clearing cache phone logs text messages emails all that good stuff and still i do weekly restarts. my biggest problem well mine at least is when im texting. if i am texting and going back and forth with a person and i receive a text as i am texting it will kick me out the text input dialogue box and send me to the very 1st message of the thread. sorry for tj
