Update: I have wiped my iPhone 3G, restored the image and then the data. It now behaves more like the 3.1.3 device in this video, actually a bit faster. I conclude that the update, if applied through a restore, does not slow down the 3G.
I have the iPhone 3G and I am not seeing any of the slowdown that shows in that video. My camera launches just as fast as the 3.1.3 and takes pictures even faster.
The big thing is making sure you do a 'restore' install rather then the upgrade and also do a full reboot after the install is comes up for the first time. This seems to make the iPhone 3G a hell of a lot faster and better and it was well reported during the beta period that this was a requirement.
Interesting, did not measure the performance differences myself. Actually I don't feel any significant differences though. So, I guess, I agree with Declan, because I did a restore install (it did not give me a choice) and a reboot too.
Sounds like a good plan. Can I restore my backup?
yes you can.
The 'restore Install' is a longer process. It wipes the iPhone clean, does a clean iOS install and then afterwards when it connects to iTunes it restores your last backup for data and settings and then has to sync all your apps and music back to the device, depending on how much data you have you could be looking at a couple of hours for it to complete.
My experience is identical to Declan's, although I didn't restore my old data. We're all using apps that backup, restore and sync over-the-air, right ;-)
Taking this approach and using Apple's iPhone Configuration Utility to create an install/restore profile will make your life much simpler at some point in the future.
True, the iPhone 3G is pretty pokey with some tasks, like initial page layout in iBooks. Stanza doesn't do any better, though.
I have a 3G. Somethings are quicker - Safari and some apps. Some slower - Settings takes a bit to come up. Just putting things into Folders seems to have sped up screen navigation, etc. iBooks does seem slow, but a) I have nothing to compare it to, b) I'm loading multi-hundred page, 4-16 MB PDFs, and c) my iPhone 4 comes July 6-8th.
Oh, and forgot to mention, I just did the straightforward install. In fact, it resolved an issue I was having with some rogue app that was causing things to heat up and may have necessitated a restore install anyway.
It's okay on my 3g - only thing I noticed is that rotating a app from horizontal to vertical view is sometimes a bit slow.
The IOS 4.0 works best on a 3GS or above due to the faster processor and 256 MB of internal RAM. It works on the 3G but with some slower performance then previous 3.1.3 OS. Also many features are not supported on the 3G like multitasking and 30 fps video. Button line, it works if you want to keep your 3G but what do you gain over 3.1.3 on a 3G device?
IOS 4 is bullshit. every new feature has been stolen from cydia. but they are worse. backgrounding f.e. is a joke in comparism to backgrounder from cydia store.
thats my opinion
