* BB5 phones are not included.

To unlock codes for BB5
models, and the important parts are within a high security smart card that is programmed by Nokia for each different network code.
In conclusion, as I know 3rd party unlocking is currently not available, only your operator can provide the necessary unlock code.
For some reasons, there's a software currently able to unlock phones such as N70, N90, etc (probably not compatible for 3rd Ed series) and it's named Unlock Me!

UnlockMe! is a software that will allow you to recover the Unlock Code actually configured in your mobile phone.
You have to install and run the software on the phone and after some minutes it will communicate you the Unlock Code actually configured in the Phone
This program it's usefull only in these circumstances
If you find a mobile phone that during startup asks you to insert the Unlock Code you will never be able to get the code using this program.

Q13: What is MMC, SD and Memory Stick?
MMC (MultiMedia Card).
The standard of this flash memory card is defined by MultiMedia Card Association. It is used in many Nokia phones although some of newer Nokia phones support SD card too.
MMC / MMCplus - 24mm x 32mm x 1.4mm. MMCplus is newer standard with higher transfer rate.
RS-MMC (Reduced-Size MMC) - 24mm x 18mm x 1.4mm.
DV RS-MMC (Dual-Voltage RS-MMC) / - 24mm x 18mm x 1.4mm - It is the next standard of RS-MMC that supports dual voltages, i.e. 3Vand 1.8V. The lower voltage is used to reduce battery consumption. RS DV-MMC can be used in the mobile phones that support RS-MMC, but not vice versa.
MMCmicro - The newest standard that is smaller than RS-MMC. It is not available in the market as the writing of this blog.
SD (Secure Digital)
The standard of this flash memory card is defined by SD Card Association.

Q14: What is IMEI? And how to show my IMEI?

IMEI = Short for International Mobile Equipment Identity, a unique number given to every single mobile phone, typically found behind the battery.
IMEI numbers of cellular phones connected to a GSM network are stored in a database (EIR - Equipment Identity Register) containing all valid mobile phone equipment.
When a phone is reported stolen or is not type approved, the number is marked invalid.
The number consists of four groups that looks this:
The first set of numbers is the type approval code (TAC). The first two digits represent the country code. The rest make up the final assembly code. The second group of numbers identifies the manufacturer:
01 and 02 = AEG
07 and 40 = Motorola
10 and 20 = Nokia
41and 44 = Siemens
51= Sony, Siemens, Ericsson
The third set is the serial number and the last single digit is an additional number (usually 0).
To show your IMEI, just easily key in *#06#.
Q15: How to get rid of "App. closed Main Error"?
