Thanks Salmal the firmware version is 05.22. Date 26-02-08. Is this version too new to unlock? Microbe
Thanks ramsee. \i tried the site but the codes did not help. The IMEI number is actually 354176029385192. Sorry misread the number written! Microbe
microbe You have only 5 tries and then it will be hard locked so stop using any code will not work. After that you will need a cable thing-a-me-jiggy to unlock it. It should still work on your Network so no big loss. I asked you for Firmware Version, insert this on your phone and tell me what you read??????? *#0000# Insert this on your phone and comfirm imei number???? *#06#
