  1. I have iphone 3gs with ios 6.0.1 and baseband 5.13.04. I installed Cydia and ultrasn0w fix 6.0 and regular ultrasn0w but i lost my messages. cant get or send them…what should i do? thanks

    • Try this, disable the iMessage app by going to the Settings app, scroll down to Messages, tap on it and then tap on iMessage toggle to disable it wait for few minutes and then ON again.

  2. nope…still cant send or resive regular message

  3. actually I can get message but its empty and from unknown sender

  4. Then you have to wait because it seems like something wrong with Apple servers.

  5. i solved a problem, did just boot in redsn0w, but i think that i have to do it every time when i turn my phone off..if i turn off phone i have to do reboot in redsnow to turn cydia on.
