This would be my first post in any forum. I have a Palm Centero with ATT. A few days back it worked perfectly. The other day I was trying to install a few apps on it hotsync setup. So, I then tried those apps but I did not find them good so I ended up uninstalling them. But later that day the phone started to slow down whiile switching apps. So I removed the battery and then fixed it right in. But after that the phone showed an error called card error. SO I removed the miscro SD card and then it booted perfectly. But then there was no sound. Please help out what should I do about it?
