Why not have a thread with the common codes that our members may need? I'll get you started with a few of the better-known ones, and no doubt our gurus will join in!

Important points before we start:
- Do not publish any numbers unique to your devices such as IMEI numbers and other serial numbers.
- Do not publish any information that is confidential to Nokia (or other manufacturers) that you have acquired by unofficial, unverified or illegal means.
- Board rules do not permit the discussion of any topic that involves an unauthorised intervention into a Nokia product. This includes any kind of hacking of the phone's identity, such as IMEI numbers and product codes.

Here we go with the well-known ones:

12345 - The standard Nokia security code. If you change this, you must keep a secure record of your new code otherwise resetting will cost you a trip to your local Care Point for a re-flash.

Some newer phones (like the shiny new 6500 Classic that we have in the Moderation Bunker, which is a 5th-edition S40) don't have a pre-set security code, you have to choose your own if you wish to activate security settings. (Please don't tell Nokia Care we've got their 6500, they'll want it back!)

0000 - The standard Bluetooth pairing code for Nokia audio enhancements (some Nokia integrated car kits have part of their serial numbers as pairing codes, if this it the case with your product, the user guide will tell you).

*#0000# - Find phone and software version information
*#06# - Find your phone's IMEI number (also on the product label inside the phone's battery casing)
*#2820# - Find your phone's Bluetooth address
*#62209526# - Find your phone's MAC address (WLAN)
*#99# - GPRS dial-up code

On Sybmian phones:
*#7780# - Restore factory settings
*#7370# - Reformat your phone (back up your personal data with PC Suite or to the memory card first!)

S40 2nd edition*
*#335738# - Clear WAP/MMS settings
*#7370925538# - Reset wallet code (But kiss goodbye to your wallet data, so I'm told...)
(*I know that these two work on the 6230i...)
