other apps I use (probably going to grow
WiFi Toggle (find it with SlideME)
Root Explorer (I found v2.10.2)
Startup Auditor (I found v2.3.1)
Advanced_Task_killer (I found 1.9.3)
I used Startup Auditor to disable a few apps that I don't need/want:
Camera (no idea why it's there)
Here's a nice site
to see what files in the system/app folder are useful and which aren't.
It looks to me a few things could be removed to free up some extra space but be careful what you remove!
