iPhone 3G w/ OS 3.1 - Problems (Slow operation)

I have the same problem. I upgraded to the 3.1 OS from 3.0.1. My iPhone 3G is not unlocked or jailbroken. After the update, the phone's functionality slowed severely. Pressing the home button, side scrolling to other home screens, placing calls, and internet connectivity all were severely slowed down.

I have iTunes 9.0 installed on a Mac Mini with Snow Leopard 10.6.1

I then, restored the phone using the iPhone restore option and then restored using last saved backup. No improvement.

I then decided to restore to full factory settings again and setup the phone as new. Some improvement noted, but as soon as I started installing apps again the slow response (in all the aspects above), returned.

I have one of the (recently removed) free memory apps, MemoryInfo, and it seems the phone on its idle state is using above 95% of the total memory. I did also notice severe battery usage, after just 2hrs of idling the phone the battery drained to 65%.

Apple Engineers - If you do read this, please issue a patch for OS 3.1 or allow us to downgrade to OS 3.0.1 until this problem is resolved.

Thank you.

I couldn't wait to upgrade to 3.1 and use video editing and genious mixes, but now my wifi is intermittent, my phone freezes, battery is draining very quickly while idling and I freeze on the unlock screen. I think these are similar issues to everyone. I just want Apple to acknowledge that these problems actually exist, its very uncharacteristic of a customer centric company like Apple to just ignore thousands of complaints. Please come out with a 3.1.1 version to solve these problems we all need our iPhones back!

Maybe thats because most people complain in forums and blogs, but never bother to contact Apple to resolve their problem.


Is this not the official Apple forum for discussion about their products and services? Is it too much to expect that the company that creates products, services, and updates doesn't utilize the spaces they've created to gather information and respond to a group rather than to an individual. I don't see how you can defend a lack of response and a lack of dialogue.

FIXED
*I went through the restore steps over at bigboss ( http://thebigboss.org/guides/how-to-restore-iphone-to-factory-state/), which restored my phone to factory. The restore and re-sync of all 14G of apps & media files took another 4 hours but as of this morning my battery is no longer draining at 40% per hour. It's like the old phone is back. I do have periodic "black screen of death" issues where the power button and home button will not restore the display, but I can fix this by plugging it into the charger or sync cable to send it a wakeup call. Way to go Apple - there's 6 hours of my life I'll never get back.*

Ok, I posted this earlier in this discussion and in other topics, but never saw any replies, so I'll post it again. The following instructions are very time consuming (up to 2 hours or more in some cases), requires erasing your phone (so save anything important, and DO NOT rely on the iTunes backup for retrieving the data), and only work on Macs (I don't know or have Windoze procedures for this).

1. Plug in your iPhone to an AC outlet (not your computer) and go to Settings>General>Reset>Erase All Content and Settings. This will take some time. It will also take the phone back to factory settings, just as it was when it came out of the box, so if you have a 3G, that will most likely mean OS 2.x. Once you've started this process, set the phone aside.

2. On your Mac, navigate to your Home folder Mac HD>Users>Your Home Folder, from there navigate to Library>iTunes>iPhone Software Updates. In there you will see a file who's name will be SIMILAR to iPhone1,2 3.1_7C144Restore.ipsw. Move this file to the trash and delete it.

3. Once your phone has completed the erase/reset process, connect it to your Mac. When iTunes opens and your phone shows up, click the "Check for update" button. This will download a NEW copy of the 3.1 update from Apples servers.

4. Once the download is complete and iTunes has updated your phone with the fresh copy of the 3.1 update you've just downloaded, it will be time to set up your phone. DO NOT RESTORE FROM BACKUP!!!! Restoring from backup will most likely restore the problem you're trying to get rid of! Now, when iTunes gives you the option, you want to SET UP AS A NEW PHONE. Once that is complete, re-sync your data. Again, NOT FROM BACKUP.

This has resolved many issues for most of the people that used this restore method, but it's not a guarantee. The reason behind these steps is that performing a basic restore does not remove the 3.1 firmware currently installed on your phone, which may have been corrupted during the installation nor does it remove the copy of the 3.1 firmware package on your Mac which may also have been corrupted during the download. Further reasoning behind this is that these steps take your phone back to a 2.x version of iPhone OS (if you have a 3G), and you'll be upgrading from 2.x directly to 3.1, bypassing all of the incremental updates in between (2.1, 2.2, 2.2.1, 3.0, 3.0.1, etc...). If someone has success with this (I did after problems when moving up from 2.2.1 to 3.0), please report back so that others will feel more comfortable performing such a daunting task.

Really bad update.

1. Dialing outbound calls just stall out, silence, they do not go through. I've waited as long as 30 seconds, nothing happens.
2. Inbound calls not ringing, no notification of missed calls.
3. No notification of new voicemail.
4. 3G Network operation does not work on occasion. After reboot, it works.

After reboot, missed calls and new voicemails appear. This is a bad, bad update. This needs to get addressed quickly, as obviously, I'm not the only one seeing severe problems.

I think I am on a track .... (Iphone 3G 16GB)

I don't know if it is important but 2 days ago I did a full restore from backup : no change

This morning (european time) I decided to turn WIFI off. At 11 PM I had 100% charge (!!!) I checked iStat that says the same. I listened music 3 hours, did some e-mail and phoned (all in all 4 hours usage and 15 standby). I almost always had very good 3G signal.

On the behavior side the Iphone behaved as it did under 3.0 (no problem at all)

I just turned WIFI again (I am at home) ... and the iphone get stuck again (slow, non responsive etc ...)

IMHO there is something that is wrong with the WIFI ...

I too use an iPhone 3G and have/had this problem. Read this article - tried what 'ferristhecat' said earlier - thanks. It seems to work !!. I also notice that there is an advanced tab under 'Fetch New Data' and it lists each of your mail accounts and fetch or manual option. I selected manual for now. I had actually turned off push some time ago as this seemed hungry on battery.
