2G iPhones previously unlocked with IPSF (iPhoneSimFree) still work after patching them with the new PwnageTool 2.0 from iPhone-dev team. I successfully updated my 1.1.4 IPSF iPhone with the original 3.9 bootloader to the new 2.0 firmware without any problems. I was using ZiPhone to update to 1.1.4 but that didn’t seem to be a problem. Signal.app is not needed as PwnageTool unlocks the baseband with BootNeuter 2.0 anyway, at least if you use all the default settings in PwnageTool’s simple mode. Your iPhone’s baseband will be upgraded to 04.05.04_G in the process. Thanks to everyone involved for making this happen! Yee-haw!

By the way: I choose to setup the iPhone as a new iPhone instead of restoring a backup the first time I connected it to iTunes after updating.

Things you may need first:

• PwnageTool 2.0 mirror: PwnageTool_2.0.zip
• Boot loader 3.9 and 4.6: boot_loader.zip
• 2G 2.0 Firmware: iPhone1,1_2.0_5A347_Restore.ipsw

Here’s a review of geotagging tools available as of today (July ’08). I tested all of them personally and tried to come up with a pro & con list on each of them. If you know a geotagging Mac application that’s not included on this list, please drop a comment. Read more »

I already wrote a few articles about how to use my preferred GPS logging device, the Holux M-241, on the Mac. In this article I’m focusing on the linking process between the GPS data and the photos. This process is called a geotagging workflow. Most of the time I’m taking pictures in RAW mode so the workflow is optimized for this type of images. I’m using a Nikon D80 but the workflow should work with almost any other (Nikon) digital camera like the Nikon D200 or Nikon D300 too. Read more »
