Hey about the unlocking of a nokia 6288 on 3

Hai,
U may try this website mobileunlocker.This site contains the unlocking instructions for Your mobile phone.Its have the unlock code and instructions for the some other nokia models.

Go to www.nokia.co.uk or the nokia site dedicated for your country. If you're not sure of the address you can go to www.nokia.com, select your counrty and then proceed from there. Then click the 'Get support & software' link on the page. Select your phone model. i.e. Nokia 6288. Then go to the Download Software tab & download the device software update. Once you've downloaded the Nokia Software updater for your device you can connect the phone to the PC using the USB cable. Follow the instructions & update the phone's software. Note: This would not work if the handset is keyguard locked as the phone needs to be unlocked so that the device can be recognised once connected to the PC. TIP: I've tried locking my NOKIA 6288 by entering the incorrect Security Code when it asks for the keypad unlock code & this locks the handset after 5 incorrect attempts but if you leave the handset ON for atleast 5-10 minutes & then try unlocking the keypad using the correct security code, the handset then gets unlocked.
