Having problems with Cydia

Hello everyone. I have iPhone running firmware 3.1.3 jailbreaked with redsn0w 0.9.4. Lately I was having some trouble with Cydia adding sources. The other problem that I was having is my iPhone doesn't ring in sleep mode, Wi-fi and You-tube not working. I decided to jailbreak it again so that Cydia can be re-installed fresh without having any error's. I redsn0w it again and I did checked the box Install Cydia. When i completed the process Cydia doesn't show any packages. When Cydia try's to update packages there is some error.

I tried jailbreaking the iPhone running firmware 3.12 with Blackr4in and installing cydia on edge . That's not working for me either.

I can't SSH my iPhone because there is no wi-fi network available where I'm right now.

I read it somewhere that you lose the previously installed packages if you re-install Cydia.

Out of frustration I un-installed Cydia.
Need your help guys before I do something stupid again.
Any reply or suggestion would be greatly appreciated.
Thanks.
