Does the process/act of jailbreaking slow down the iphone (or cause instability) in any way or does it slow down once you add apps? I had previously JB my iphone and found it getting really slow despite only installing winterboard with just one theme (theme was "touch") -thats it. Safari crashed a lot and apps would take 20 seconds to load. I used pwnage tool (not quick pwn)... I've searched the internet on this and I find support for both arguments...
1) JB'ing slows phone down and causes instability
2) JB'ing is fine. Its the apps you install that can cause problems
So in reference to the original poster's question.... i thought I would propose this to the thread for discussion because I myself get confused with the pro's/con's of the whole jailbreaking process.
