I have some problem with camera these days.. I have updated to 2.3 in august. At that time, all the features were work perfect. Unfortunately, I'm facing the camera issues last two days ago. I thought that is the software error so I tried to repair my phone with SEUS but it can't solve. When I open the camera, it shows camera is not available or sometimes restart itselfs or sometimes it works perfect.. What's going on?????? Pls help me!!!! 
Hi, it could be a hardware problem if software repair is not able to resolve your issue.
Anyway, a long shot, test camera with another SD Card.
eeeks~!!!!............... my phone camear is gone..
I love camera.... 
go to settings -> applications -> manage applications -> all -> camera
clear everything
ha ha.. I already tried this method.. it can't help..
If it's the hardware error, can restart the phone itself when open the camera???
Probably a hardware problem, which I think your only option is to send phone to your local SE Service Centre for repair.
That's xo sad... no loacl service center in our country..
Here's the contacts, see which is the nearest, http://www.sonyericsson.com/cws/corporate/common/contact/phonelist
