Thank you very much for sharing this. I posted these comments on the youtube video and thought they might be helpful here as well:
Didn't work for me. I SSH'd and put it on the ipad and rebooted the ipad and a white icon for mobiletimer showed up and when I try to launch it-it crashes/does nothing. I did the SSH and upload of mobiletimer from a windows machine. I uploaded the main MobileTimer.app folder and not the ._Mac_OS one. Any suggestions? Does it have to be done with a mac.
update: apparently I had to set permissions recursively to 755 for the folder after I uploaded it, now the app launches but it still has a blank white icon. Hoping someone knows a fix for the icon problem.
Update again: Downloading any app from cydia will fix the icon for the MobileTimer. I guess something cydia does when installing the app must force a rebuild of the icon cache or something.
Last Update I swear: just wanted to mention that for some reason after putting the mobiletimer app on my ipad it broke my wifi icon from showing up when connected to wifi. If this happens to you too, I found that under the settings app>General>reset>Reset Network Settings, fixed that. I had to do it twice I think but then the wifi icon started showing up again after that. Also a quick way to rename the icon from "MobileTimer" to clock can be done by grabbing an app from cydia called Rename
