don't u have a feeling it's a conspiracy... they give you the upgrade knowing it will cause problems and of course we want to buy a new phone... i normally always buy the new products immediately but this time i'm just not that motivated to buy it..
I'm sure they will solve some of the problems with a future update. The same thing happened when 2.0 was released. It was buggy as hell. 2.21 was perfect for me. Wish I had stuck with it for a while longer until Apple put out 3.01
I find 3.0 to be the most stable of all the revisions. I don't notice much lag however, the lag I do have I attribute solely to the jailbreak. I was in the Apple store the other day and played around with the new 3GS and that thing is very fast compared to the 3G. Still doesn't make me want the S as I am going to be patient and wait until next summer to see what Apple has in store for us. My upgrade eligibility date is in September. I hope I don't get tempted!
I really don't see how that would fix lag permanently. I believe the lag is based more on the hardware and memory specs, more than just clearing settings.
You have to remember the iPhone is a mini computer, and in order for it and any other PC / Mac to run properly, it has to have enough memory and contain a fast enough processor. Without that the system will just run like crap no matter what you try and do to it.
I'll definitely give it a try when needed, although I doubt it will do much.
I thought it was just my perception, but the phone does feel a bit slower with 3.0.
Two places that I notice it being slower. If I open an app immediately following the closing of another. The next app is really slow to load. Its as if there is some residual activity after closing the first app. Perhaps its flushing swap memory or something.
Also entering the first character or two of a text message or search will be laggy. It takes a moment for the phone to catch up.
That's what I felt also. Lagging letters while typing was killing me! My friend and I started thinking conspiracy! That maybe Apple intentionally slowed down the 3g to make the 3gs seem even faster! But lagging letters...I'm sure it wouldn't be accepted by Apple standards. I was thinking that Apple will fix this in a patch release or something...but I got impatient and started looking for solution.
My phone was DEFINITELY slower! took a long time for a keyboard to pop up, and when I hit the home button, there was a long pause then the home screen appeared right away, instead of the familiar "zoom" effect. I recently did a restore from iTunes, and that seems to make a big difference. Try it and see what you think.
I ended up restoring as a new phone last night. Yesterday the battery just started draining crazy fast. It was almost dead by 2PM with 2 1/2 hours use. This happened to me before witht he 2.1 update and I ended up getting a new iPhone from Apple. Anyway, the restore has worked very well so far. Everything is snappy again like it was before I updated to 3.0. Still having some issues with wifi connectivity.
