A) PREPARATIONS
Download and install the latest version of iTunes (7.6):

Remove the PIN-code on your own sim-card using a "traditional" celluar phone.
Put your own sim-card in iPhone.

Before starting:
- use usb-cable directly in iPhone, don’t use the iPhone dock (easier using only the cable)
- uninstall ALL applications and Sources in Installer….

B) UPDATE / RESTORE iPHONE to the LAST FIRMWARE-VERSION
There are two reasons for running through an update/restore in iTunes.
First for updating to the lastest baseband (04.03.13_G),
secondly because ZiPhone "demands" that iPhone are "paired" with iTunes.
(for OTB 1.1.3 the restore is for "pairing" with iTunes, it has already baseband 04.03.13_G)

- connect iPhone to the computer w/usb-cable
- start iTunes
- turn on iPhone, wait until iTunes recognize iPhone
- click Check, click OK

Now you must choose one of 3 choices in iTunes (it depends in what condition/firmware the iPhone is in right now)
a) if button Check for Update is active (ie. not dimmed):
- click Check for Update, click OK (if iTunes say that you have the latest version continue nevertheless to the next line)
- click Restore, click Check, click Restore, wait…. continue with B2

b) if only button Restore is active (ie. if buttons Update or Check for Update are dimmed):
- click Restore, click Check, click Restore and Update, wait…. continue with B2

c) if both buttons Update and Restore are active:
- click Update, click Check, wait…. continue with B2

B2 - Finish and quit iTunes
After the update/restore is finished (4-5 min.):
- wait until iTunes recognize iPhone, ignore error messages regarding non-supported SIM-card
- click iPhone’s eject-icon in the left panel (in iTunes)
- quit iTunes
iPhone-display is showing "slide for emergency" over a picture of a usb-kabel –> iTunes-icon
