iPhone useful information

Here is some useful information about iPhone.

iPhone "root" and "mobile" user account password

on my iPhone 3GS, the passwords are:
The password for root is "alpine"
The "mobile" user accounts password is "alpine"

on older iPhones, the passwords might be:
The password for root is "alpine"
The "mobile" user accounts password is "dottie"

I suggest you to change the passwords.


How to capture iPhone screen shots

I was just about to search for any apps to capture screen shots, then I found iPhone already have this feature.

Just press the "home" button and the "power/sleep" button at the same time, after a "click" sound, a capture of your screen is in your photos' camera roll.

Very nice! Should also work on iPod Touch. Try it.


iPhone folders

Ringtones:
/Library/Ringtones

Photos/Videos (camera roll):
/User/Media/DCIM/100APPLE


Where is iPhone Backups

iTunes makes backup of your iPhone automatically.

Where Backups are stored

iTunes places the backup files in the following places:

On a Mac: ~/Library/Application Support/MobileSync/Backup/

On Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\

On Windows Vista: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\

Since iTunes only keeps one backup per device, you should save a copy of the backup in other places.


Putting Iphone/Ipod Touch into DFU mode

Enter DFU mode

Here's how to enter DFU mode with the Iphone/Ipod Touch:

1. Fully turn off your Iphone/Itouch. Make sure it's plugged in into your PC/Mac if you want to flash something (which you probably want to).

2. Hold down the home button, then hold down the power button without releasing the home button.

3. When you see the Apple logo, release the power button, but still hold down your home button.

4. When you see a white screen, you are in DFU mode.

This could be handy if your Iphone/Itouch fails a flash.


iPhone troubleshooting - stuck at white screen

First time encountered this problem. I used up the iPhone battery and tried to charge it, but later I found it was stuck at a white screen. Cannot turn on or off.

The solution I found:

To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds. During this time, a red "power off" slider may appear and the screen may go black, but do not release Sleep/Wake and Home buttons until the Apple logo appears.
