About a month ago, I had to rejailbreak my phone so I could update to the latest firmware using PwnageTool 3.1.4. Then I noticed it wasn't showing "AT&T" or the E or 3G network up in the corner. Someone told me to install Ultrasn0w to fix this, which it did. But I didn't realize that either the ultrasn0w or the last jailbreak took away my visual voicemail. I just thought noone left me messages ... now I'm stressed. Is there a way to fix this?
