This was my phone till I lost it (forunateley just before contract renewal). I've got a new phone now and I've just found the K800i in the garden. The phone was blocked by O2 when I lost it, but I want to give it to the MRS so she can use it on PAYG. O2 say the phone is now unuseable and can't be unblocked without screwing up my present sim card ! is this correct and is there any way to unblock it cos it's still a decent phone and she might as well use it ?
