I searched, haven't found anyone with this issue. Using an AT&T iPhone 4 with 4.3.2 firmware. I purchased Dimmer from Cydia, and after installation it requires a respring. After the respring, the phone is in safe mode. I tried disabling all of the SBSetting Mobile Substrates, reboots, resprings, nothing works. The only way to get the phone back working is to uninstall Dimmer. I have lockinfo installed (and several other jailbreak apps) but when disabling the lockinfo mobile substrate, problem was still prevalent. Tried to reach the developer via support forum, but haven't heard back. Anyone out there see this, or solve it? Thanks!
