there you go.
titanium backup and restore causes so many problems when not used exactly correctly. there are many posts regarding sourcery and links (if they still work) on what to do with titanium and what not to do.
I can guarentee you that sourcery does not lock up, freeze, force close, crash, or have any other problems when installed correctly than apps added as they should be installed not restored. especially when restored from backups from gingerbread.
if you do it this way im sure you wont have problems.
if you dont want to go through this than thats cool too. but even though we have ceased sourcery and stated no support we do try to offer what we can at this point. soucery is still one of the most feature full roms out there. But we do not offer support if titanium has been used due to its long history of causing problems on many roms(not only sourcery).
It has been designed to minimize lag as much as possible but the memory on the droid is just not adequate anymore. But i use this latest build of sourcery daily and have not had any problems and up time is over 2 months. I use it mainly for netflix now since i have a g2x. but its still fully functional darn best money i ever spent. never regretted buying the droid 1 time. now the g2x thats a different story.
Good luck hope you get your phone to work as you want it.
