iOS 4.1 beta shows performance improvements for iPhone 3G

Ever since upgrading to iOS 4.0 my iPhone 3G performed like a piece of crap. I’ve seen that Apple published an iOS 4.1 beta on its iPhone developer network website and I was willing to give it a try to see if there are any performance improvements. To make it short: yes, there are. While it’s not as good as with v3.x the phone is a lot more responsive than with v4.0 or v4.0.1, without having to turn off Spotlight indexing! Let’s hope these changes make it to the 4.1 GM.

To activate iOS 4.1 beta your iPhone’s UDID needs to be registered with an Apple iPhone SDK account ($99 a year). As every account comes with 100 UDID slots for iDevices you just need to find a developer who adds your iPhone’s UDID to the beta SDK list. Some do it for free, some charge a couple of bucks to do it. I may have one or two UDID slots left in my dev account so you may want to leave a comment if you want to have your iPhone registered (please provide the UDID for the iPhone- but don’t ask me where to look it up). You also have to find the beta firmware on your own (Torrent sites may be a good place to start). Sorry, I don’t have any more UDID slots to give.

Btw. initally I tried to install iOS 4.1 beta on my iPhone 3G without a registered UDID. I used redsn0w 0.9.5b5-5, iOS 4.0, iOS 4.1 beta and iPhoneExplorer to remove the beta-tag in SystemVersion.plist. While I was able to activate my iPhone 3G that way I lost 3G/WiFi network connectivity. The problem seemed to be related to DNS. Making/taking calls, SMS worked perfectly though. This way of activating a phone most likely requires a new redsn0w version in order to work properly.

iTunes: The required file cannot be found

Lately, I always get an error message when I try to sync my iPhone in iTunes. The message simply says “The iPhone cannot by synced. The required file cannot be found.”

Unfortunately, iTunes doesn’t say exactly what file is missing. While playing with the sync options in iTunes I found out, that the problem is related to Apple Aperture 3 in my case. If you’re using iPhoto instead of Apple Aperture, you may find a solution in this Apple support note. If you’re getting this error message in iTunes and you’re syncing your Aperture 3 library (or parts of it) to your iPhone, I may have a solution for you. Continue reading

Apple Aperture 3 flickr upload lacks GPS data… not!

Ever since the release of Aperture, Apple only half-heartedly supported metadata in exported photo’s. I don’t know why but Apple decided not to export extremely useful metadata information like lens model and many others as well. Unfortunately, this is still the case with Aperture 3 :( Lens type is still not included in any exported JPEGs or when directly uploading a photo to flickr. When I tried to upload a photo to flickr using the new flickr button in Aperture 3, even location data from “Places” wasn’t included. Commenter Connor had the solution: I needed to check that checkbox in Aperture’s preferences web tab (see screenshot below). Continue reading

Aperture 2.1.3 fixes (some) missing EXIF export tags…and more!

Yesterday, Apple released a new version of it’s photo management and raw conversion software Aperture. The issues addressed include:

  • Nikon images imported using a direct camera-to-computer connection now display thumbnails correctly in the Import window.
  • Fixed an issue that could cause duplicate image versions to be created after rebuilding a library.
  • Fixed a library issue that prevented operation of the Relocate or Consolidate commands in some circumstances.

The fixed import-thumbnails issue is great news for Nikon D700 users. Finally, we’re able to see what photos we’re about to import from our camera. I also checked if they fixed an annoying EXIF metadata export issue when exporting a photo – and to my big surprise, they did!

EXIF data

EXIF data

As you can see in the screenshot above, EXIF Viewer displays the latitude/longitude metadata information in an exported Aperture photo when using Aperture 2.1.3. The master image was a raw camera file which I exported as a JPEG. Unfortunately, lens information is still missing in the exported photos :(

Jailbreak/Activate IPSF 1.1.3 iPhone with 04.03.13_G

The 1.1.3 soft-upgrade is called a soft-upgrade because it won’t update your baseband firmware to the 1.1.3 software level (04.03.13_G). This was necessary because as of today there’s no anySIM hack for the new baseband.

Added 2008-2-23: You don’t need if you run anySIM 1.1.3 on your IPSF iPhone. I just tested it today and it works!

Added 2008-2-29: Looking for 1.1.4? See here!  

If you own an iPhoneSimFree’ed (IPSF) 1.1.2 iPhone (or 1.1.1) with the 3.9 bootloader you’re able to fully upgrade to 1.1.3 including baseband! Why would you want the new baseband if you could run 1.1.3 with the older baseband firmware? I don’t really have an answer to that. I just wanted to make sure the software and the baseband firmware in my iPhone are on the same level as intended by Apple’s software engineers.

Uneven iMac Displays

Test your aluminum iMac if it has a good or bad display


Added 2008-4-1: Apple being sued over iMac display quality!
“Dazzling displays: Your photos, movies, and games will come to life in rich, vivid color thanks to the new glossy widescreen display on every iMac. …delivering greater performance for everything from enhancing photos to playing games and more.”

This is how Apple describes the displays in the new aluminum iMac. But there seems to be a vast difference between the marketing promises and reality. Users affected by bad iMac displays report their experiences as follows (these are just a few excerpts out of dozens of statements in Apple’s own discussion forum):

“I’m a PC-to-Mac switcher and purchased a 24” imac about a month ago and returned it for a full-refund due to the obvious gradient.”
