I went back home and swap my phone card to that phone again and after that I put the phone card back to my phone and thank God, I can switch on my phone in my treo again. Don't know why.
What I think is the phone I borrow to use my phone card is a Nokia phone and it has delivered notification for the sms I have sent. But treo can't able to receive that kind of delivered notification.
At first, my treo says I have sms and ask if I want to save it to my phone or not. At first I say yes and it started to crash since then.
The second time, after I swap phone, I receive the same question but this time I said no and it works since then.
