HAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA... Quoted for DECIET. Wow. I'm going to assume that your statement was in jest because I don't want to believe we have that many dumb people on Macrumors.
Computers, and the iPhone is just that, slow down when more applications are running. JAILBREAKING does NOT slow down your phone. Installing so much there is no virtual memory/page locations left does. Running too many background apps will (only possible when JB'd). Nothing inherant about the process does slow down your phone.
Like I mentioned. My phone is Jailbroken and I keep plenty of free space and don't use any backgrounded apps and don't use Winterboard. I'll put yours side by side with mine any day to prove to you that mine runs just as fast.
If you know nothing of the subject of memory usage and how programs run, don't go here spewing feces around the forums about how "it's proven!!! Look at Youtube where sum nubbie installed a bunch of crap on his phone and it now runs slower!"
Take a class about computer architecture and tell me how jailbreaking a phone (removing a signed software check) would slow anything down. Until then... don't talk.
SUMMARY: Jailbreaking doesn't slow down your phone. It just gives an idiot the power to do that themselves. If you can't handle the power, don't do it. Also, don't complain that jailbreaking lagged your phone. Instead say, "I installed too much junk and now my phone runs slow"
This post alone should have it's own place on the main page of these forums.
