1. Download iPhone OS 2.1 IPSW: [iPhone (first generation) | iPhone 3G]
2. Turn off your iPhone by holding down the sleep/wake button.
3. After the phone is off and hold the sleep/wake and home buttons at the same time for 10 seconds.
4. Release the sleep/wake button; continue to hold down the home button until iTunes detects the iPhone in “recovery mode.” Your iPhone is now in DFU mode.
5. Hold down the option key on a Mac or alt key on a PC and click “Restore” in iTunes.
6. Locate the IPSW file and select it.

Disappearing apps (cont.) Dozens if not hundreds of users have now reported a problem in which various iPhone applications, both third-party and included, disappear after the update to iPhone OS 2.2. In some cases, the afflicted iPhones were jailbroken, in others, they were not.

A sampling of reports from iPhone Atlas readers:

• “When I upgraded, all my apps non-original apps disappears, except for google! When I tried to re-download and then resync them onto my iphone, only some of them would appear. After talking to support, we tried starting my computer (she said this was happening to some people) and then syncing. This added a couple more, but about 10 were still sitting in my itunes and refusing to sync.”
• “After the os 2.2 update. Safari suddenly disappeared. Syncing etc didn’t work or resolve the issue. I had to do a restore to get things back to normal.”
• “After upgrading to 2.2 the iphone camera app disappeared, and every program that uses the camera stopped working also. Restoring the phone brought it back but then the next Sync made it go away again. Very annoying. How much QA did they do before they released this upgrade? I can understand third party apps breaking but not the base applications.”
• “I also have had a problem with a missing application. My camera application has disappeared and I tried restoring it, and it appeared for about five minutes, let me take one picture, then was suddenly gone again.”

Possible fix: Setup as a new phone Try setting your iPhone up as a new phone then re-downloading an missing applications. To do this, perform a restore in iTunes, then choose “setup as a new phone.”

WiFi cannot connect (cont.) Perhaps the most widely reported problem after disappearing applications is one in which WiFi connectivity fails after the iPhone OS 2.2 update.

Reports from readers:

• “Slowly updated my iPod Touch to 2.2 and now wifi does not connect. Get the check mark but no ip address is assigned. Tried renewing and rebooting. This is a step backwards.
• “I cannot connect to my wifi at home and I never had a problem in the past.”

In some cases, “forgetting” the currently configured network and then reconfiguring it can resolve the issue. Other potential fixes include:

• Switch the router to WPA2
• Remove all spaces from the WPA pass phrase
• Remove all security from the router until a stable connection is attained then reconfigure the security

Cannot sync with iTunes Several users have reported an issue in which they are unable to sync with iTunes after the iPhone OS 2.2 update.

One reader writes:

After the update to OS 2.2, iTunes is unable to completely connect to iPhone. iTunes message says I must restore iPhone to original settings. iTunes shows iPhone on side menu, but only partially. And I have no access to its contents. (For example, iTunes is unable to say the memo usage, or even the iPhone’s name. It just shows ‘iPhone’ and nothing more, instead of ‘Andre’s iPhone’ and 2 GB used memo.”

There are a number of potential fixes for this issue. Among the most commonly successful:

• Reinstall iTunes 7.6.1 (Mac/Windows) Simply download the package, run the installer and restart.
• Check the USB port Make sure that your iPhone is connected to a normally powered USB 2.0 port. If you’re using a hub, try connecting the iPhone directly to the computer or vice versa. Also try switching ports.
• Turn off auto-lock On your iPhone, tap Settings > General > Auto-Lock and set it to “Never” then re-attempt syncing.
• Restore the iPhone Click the Restore button under the Summary tab. Restoring the phone will erase contacts, calendars, photos and other data on the phone (including any third-party applications), but will restore automatically backed-up information including text messages, notes, call history, contact favorites, sound settings, widget settings, etc. Some users have reported that restoring the iPhone, but not restoring custom settings data from the computer-stored backup alleviates this issue. Note that you’ll lose text messages, notes, call history, contact favorites, sound settings, widget settings, etc with this method, though you can restore them anytime by simply doing another restore and choosing to push the backup to the phone.
• Play the isolation game Leave your iPhone connected (or plug it in if it is not already connected). Deselect all sync options. This requires going to the Info, Ringtones, Music, Photos, Podcasts and Video tabs and unchecking every box. Sync your iPhone. Note that this may result in deletion of some data from the iPhone. Re-attempt a sync with all of your normal options. If it fails, try checking only one or two sync options and repeat the process until you find the problematic sync data.

iPhone OS 2.2: Saved Image Bug

November 28, 2008

iPhone user, Brandon Lain has posted an image flickr about the discovery of a bug in the iPhone OS 2.2 when saving photos. According to Brandon this was confirmed by another iPhone user, Scott Johnson, who indicates that the iPhone is indeed “upscaling a thumbnail of the downloaded image.”

Apparently, under iPhone OS 2.1, images saved from an email message or website that were larger than the native resolution on the iPhone were scaled down, with a resample resulting in a clear image on the screen. iPhone OS 2.2, however, does not perform the resample, and therefore yields a fuzzy and pixelated image.

The site goes on to detail how you can recreate this bug yourself:

“Try this out yourself. On your computer, resize one copy of an image to no more than 480 pixels on the long side and a second copy to about 640 pixels on the long side. Email both to your phone, and save them to your camera roll by tap-holding on the images in mail then selecting Save 2 Images.”

Next, open the Mobile Photos app and see the results for yourself. You’ll note, like Brandon that the 480 pixel image will appear normally, but the 640 pixel image will be fuzzy and pixelated.

2G iPod touch Processor Clocked Higher than iPhone’s?; Benchmarks

November 28, 2008

TouchArcade reports that the second-generation iPod touch’s processor runs at 532 MHz, while the iPhone 3G’s processor runs at 412 MHz.

Both the iPhone and iPod touch use an ARM processor capable of running at 620-667Mhz. However, it appears that Apple down-clocked the processor in production devics, presumably to conserve battery life.

Nearly a year ago, iPhone Atlas broke the news that iPhone OS 1.1.2 delivered slight boost in operating clock speed. iPhones running firmware/software version 1.1.1 displayed a clock speed of 400 Mhz and a bus speed of 100 MHz, whereas iPhones running firmware/software revision 1.1.2 displayed a clock speed of 412 MHz and a bus speed of 103 MHz.

As such, it’s possible that Apple will boost the iPhone and/or iPoud touch’s processor clock speed with a future software update. Given battery concerns, however, such a move may be unlikely.

Meanwhile, a Polish site has performed benchmarks of the first-generation iPod touch, second-generation iPod touch, first-generation iPhone and iPhone 3G. Their results (higher numbers are better), would appear to confirm the original finding:

• 1G iPod touch software 2.2 - 99.039
• 1G iPhone software 2.2 - 99.422
• iPhone 3G software 2.2 - 104.23
• 2GiPod touch software 2.2: 2.2 - 145.20
