I understand that a lot of people are happy with 2.1 because 2.0 was a particularly slow firmware. However, I am not impressed by the speed of 2.1 either. Maybe because I 'resisted' on pwned 1.1.4 until few days before 2.1 came out to custom restore 2.0.2 and after a couple of days I was already on 2.1, and so I was able to make a comparison between 1.1.4 and 2.1, or maybe it is my machine, who knows, but I think 2.1 is pretty slow. Is there any fix for its slowness, something that makes it faster?

try a DFU restore....but i agree 1.x.x was faster on my phone than 2.1

Yes, and what's worse, the network strength has deteriorated (lots more "No Service" than under 1.1.4, with both versions of the baseband firmware). You have the same experience there?

ye im expierencing a lot of no service areas its pretty lame

"Reset All Settings" made my 2.1 way faster than it was before.

that rest all settings really improved the speed of my phone thnx man

The weird thing is I was very happy with 2.1 at first. And then my iPhone began to become slow.
I don't want to restore because I don't trust quickpwn to activate my phone in a way that resists further updates but this is seriously bugging me.

Tried the reset, and it's still sooooooooooooooo sloooooooooooooow.

Seriously, most companies update firmware to fix problems, not to take a huge leap backward!
