Right now I am using the 1.0.2 hack for my iphone and avoided 1.1.1 since it was troublesome at best. However, now we got the revirginize method and pretty easy activation method, is it a good move to update to 1.1.1?

If you need things that comes with 1.1.1 then upgrade. If not, dont.

Does the sound volume really improve?

I thought the sound volume was very noticable. Its still not great but its definantly better.

what about speed? does it seem to run more smoothly? with or without summerboard.

I am not upgrading yet... I don't see a need to yet... not worth the risk.

If it's not broken... does it need to be fixed?

It's the ". " shortcut that convinced me to upgrade

So yes... it was for me. Though I just did it 2 days ago, so it was relatively painfree. CARNIVAL + anySIM was really easy, but it's even better now with the newest one-step unlock method....

i dont think its worth it. I had 1.0.2 unlocked via AnySim1.0.2 and everything was working fine. And for some reason i decided to revirginize it. Methods for doing so after reading and researching the forums here and at elite were quite easy with a minor waiting for data hang up. But personally its the same. i have summerboard and SSH and such installed and i think its slowed down again, not sure if any of you have noticed the sluggishness of the phone after installation of even 1 or two apps but yeah its still like that in 1.1.1. in the end its up to you. If i could go back i wouldnt have bothered but i guess i wanted to fix my seczones
