Can I modify default photo numbering?

[sbimos]

Early 3GS iPhone running 3.1.2 via PwnageTool 3.1.5. Using a Mac.

On a few occasions, I have had to reinstall firmware on my iPhone. When I restore my apps/settings from iTunes afterwards, I noticed it always resets my photo numbering back to "IMG_0001".

Does anybody know where/how the count is stored? I would like to modify the number so it picks up where I left off. "IMG_0999" for example.

Thanks

This is a brief guide to [re]setting your default iPhone camera photo numbering.
(derived on a Mac, using 10.6.2, early 3GS iphone running OS 3.1.2 via Pwnagetool 3.1.5)

Needed:
iPhone Explorer (1.183 used)
Pref Setter (1.2.2 used)

-pictures attached for additional clarity.

00. *I cleared removed all photos from the camera role before beginning.*
01. Connect your iPhone USB and start iPhone Explorer.
02. Hit the "change root" button.
03. Pick "var/mobile/media".
04. Navigate to "/DCIM/.MISC/" and select "Info.plist".
05. Drag a copy of "Info.plist" to your desktop.
06. Start Pref Setter and open "Info.plist".
07. The Integer 'Value' you see is for your photo numbering (mine shows "415")
08. Click on the value and change it to any number you wish.
09. Save your modified "Info.plist".
10. Drag it back from your desktop to the same directory in the iPhone Explorer window, and replace the original.
11. *I restarted the iPhone after this procedure, prior to any new pictures.*

I tested this under 4.0, but it stopped working under 4.0.1. I'm not sure what happened. =(

This is a brief guide to [re]setting your default iPhone camera photo numbering.
(derived on a Mac, using 10.6.4, iPhone 4 running iOS 4.0)

Needed:
iPhone Explorer (2.0 used)
TextEdit
iPhone (no need to be jailbroken)

00. To make life A LOT easier, make sure you have no new photos left on the iPhone. Suck them out with iPhoto or whatever, deleting the originals. Leaving new photos on will SERIOUSLY screw with these instructions.

01. On the iPhone make sure you are NOT running the camera app. Also, (iOS 4+) make sure the camera app is NOT running in multitasking. To do this, double-click the home button, swipe through the docked multitasking apps until you find the camera app or not, press and hold the icon in the dock until they "jiggle", then press the minus sign on the upper corner of the app to close it.

02. Connect your iPhone USB and start iPhone Explorer.

03. Navigate to "iphonename/media/DCIM/.MISC/" and select "Info.plist". Option-Drag a copy of "Info.plist" to your desktop.

04. Drag the copy of "Info.plist" into Textedit. It should look something like the following sample. For every 1000 pictures you take, the iOS modifies the "key" & "integer" line. The key is each 'group of 1000' that your count has gone into, and the integer and the highest count photo you have taken into the group. For example, (see following) LastFileGroupNumber-103 is into the 3000-3999 photo count, and the associated integer 223 says 223 photos have been taken in that group. Therefore, the photo numbering is up to 3223. If the LastFileGroupNumber was up to -104, you would be in the 4000-4999 photo count range.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>LastFileGroupNumber-103</key>
<integer>223</integer>
</dict>
</plist>

Modify per your needs. If you want to start numbering at 4500, for example, you would have to modify both lines:

<key>LastFileGroupNumber-104</key>
<integer>500</integer>

05. Save your modified "Info.plist". Drag the file back into the Phone via the iPhone Explorer window, replacing the original.

06. Once you have copied your Info.plist back to the iPhone, and added any needed folders, you are almost done. Simply restart.

Enjoy.
