I've read several threads but cant seem to get the answer im looking for. Maybe someone can clear the air for me. I'm currently running 3.0 but want to update to 3.1.3. I'm also currently jailbroken. My question is if i update to 3.1.3 firmware, will I lose everything ive loaded via cydia? Examples: sbsettings, themes, etc. I'm assuming yes, but would really like to know a definitive answer before i decide whether to upgrade or not. Thanks in advance. DZL1.
