iPhone 3G Lag is intolerable! Video examples included.

My iPhone 1st gen running 2.0 is doing the exact same thing. The problem is most severe in address book. While my address book is somewhat large (about 600 contacts), I did not have this problem until immediately after upgrading to 2.0. Apple, please fix this!!!

So what is the consensus at the end of all this - should we be returning the phones or waiting for new firmware? My iPhone can get itself in such a state (slow, sticky, freezes, poor signal 3G/WiFi) the only way out is to power off/on.

Don't return your phone - I would never personally do this since once the performance regressions get sorted out (and they will in the next bugfix update), it's just the greatest personal device.

Totally agree with the last comment Milen, but we do need to be vigilant - hardware issues are one to watch out for - I'm hoping it's software too.

The slowdowns are definitely software issues. Here's one way to verify that the Contacts app initial lag is programmer error - select the "Contacts" tab in the Phone application and launch it while trying to scroll immediately after it opens - there should be no delay (if you see a delay, it's only the first time contacts are loading into memory, try it next time and there will be no delay). So both apps load the same information but one has a lag and the other one doesn't - it must be a the software (in that particular case).

Regarding the hardware - I had two dead pixels and the screen was acting a little bit weird, so I went to the Apple Store (Regent Str, London) and got it replaced in 5 minutes with no fuss. So if your hardware is acting weird, just book an appointment and the guys at the iPod Bar are gonna be happy to check your iPhone out.

Good observation, i can confirm that behaviour here too (phone versus contacts app). Do you have signal issues by any chance? Mine can go for ages without problems then suddenly it can't find a network, either 3G or WiFi - actually WiFi seems a little weak, it rarely finds the hotspots outdoors and often drops out the indoors (AEX).

SAME EXACT ISSUE HERE! I THOUGHT IT WAS JUST ME! FIX IT APPLE!

I haven't noticed any signal issues so far but I usually don't look at my iPhone that often since it sits in my pocket - I use it mainly for its data capabilities and not for the voice.

I just did! Thanks, hope Apple responds.

First time Iphone user...finally out of my contract with old carrier so I got it, 16g white.
I bought this after owning the ipod touch and luving the interface...it was snappy. Lag definitely an issue....

I notice it most when unlocking the phone from sleep....it can be that it just takes an extra second to open the phone or sms app...it acts like I never touched the "button" for the app.
I have also seen the laggy typing once or twice in sms app. Just exited the app and went back in, lag was gone. Certainly feels like a memory/software issue.

I am on the last build of firmware from Itunes (had to restore since itunes tried to set up my iphone as my jailbroke Ipod, things got funny then).

In the end I think it depends on how you use your phone...what you are switching between all the time and what not. Firmware update should sort it out....it better.

They have 19 days and my phone goes back. I won't accept crappy performance from a $300 phone.

I couldn't agree more. This is totally unacceptable, Apple. I've waited a year for you to get the software/hardware debugged, now I'm not sure it was worth the wait. I've experienced the same lag with contacts (>3000, I know that's a lot), mail, and home screen. SMS Text is also very sluggish (5-8 seconds to pull up application). This stinks.

The number of contacts have nothing to do with it. I sync 36 contacts with exchange and experience a lot of the same lag.

I can now say with absolute certainty that my 3G iPhone is currently the most frustrating piece of technology that I own. MobileMe is a close second. In contrast, my first-gen iPhone running 1.1.4 was the best piece of technology that I owned.

Just a thought: If Apple doesn't read complaints / issues posted by their customers on an official, Apple-hosted support forum, then that speaks volumes about how Apple views it's customers.

I agree with the amount og contacts not being indicative of the amount (if any) lag. I have about 100 contacts and suffer from the demon lag in both the SMS and contact sections. I have put the new build on and still see the issue.

Of note, I have remote, google, ebay and holdem apps installed. I notice the glitch quite often after I use the hold'em game.

I agree with others in that it seems that the program is not closing and that this makes it feel as though RAM is low.

I sure hope apple fixes this soon.
