its not working "correctly" for me either. it will change animations speed just fine, respring, and its quick. but if i multi task (double click home button, built in ios multi tasking), it goes back to stock speed. which is weird because i used it before flawlessly. when i updated to 4.3.1 i decided to try springtomize (which ate RAM and caused crashes all the time for me, ymmv), and have now switched back to fakeclockup and am having this problem. any ideas. oh, btw, i am still on 4.3.1 and will be updating to 4.3.2 tonight. hopefully a "erase all content and settings" will fix it, as i didnt realize that didnt work on jailbroken devices...mine just reboot looped for 4 hours til i got sick of it and hard rebooted. so this time i will erase content and settings, update to 4.3.2 official, erase content and settings again, and restore to a jailbroken 4.3.2 and test it on the new firmware.
