Had this since new in 2006. Since being given a work mobile, it's only been used as my PCs SMS portal (via bluetooth). Last worked in November.
Been kept charged all the time.
Out of curiosity, when to check it, and it's now asking for a "Phone Lock Code" which seems to be 4-8 digits.
This is *NOT* the "PIN" code, as it seems to allow any number of wrong guesses without locking the phone. In fact I wish it *would* lock the phone - I have the PUK.
O2 (original source) support are useless, just saying "I must have put the code in" (I ****ing well didn't).
Googling isn't much help.
Anyone experienced this, or have an inkling as to what's going on ?
