My phone has gotten hideously slow. Woudl backing it up, completely wiping it clear, and then restoring the apps & data make it run at all faster, or am I just blowing smoke up my own ass?
You can overclock it, but that makes it run hotter and also runs down the battery. Two suggestions, first do a hard reset. If that doesn't work then hook the phone to iTunes and do a restore as new. I have a 3GS that is jailbroken and it runs everything fast. There must be something in your phone that's causing it to bog down and restoring it should cure it.
