I reinstalled all my apps from Titanium after flashing Leedroid last night, but Facebook stopped working - the programme opened up ok but wouldn't update (I suspect I may have messed this up when I reinstalled everything) so I tried to uninstall Facebook via Titanium in the hope that I could reinstall from the market. But that hasn't worked as Facebook has disappeared from Titanium but remains on my phone, recognised in Market as "Installed" and still not working. I have found the Facebook app in the LeeDrOiD .zip file on my SD card via Astro (/mnt/sdcard/LeeDrOiD_v.2.2f_A2SD.zip/system/app/Facebook). When I select the Facebook file I get the "Application File" window up, showing "Browse File" and "Open App Manager" options. When I select "Open App Manager" I get two options: Uninstall or launch. If I uninstall from here, can I then reinstall from Market, or is it more complex than that?
