OK - I have a 7210 that my mate has 'lent' me - as he smashed my missus's 7210 pissed up at our house the other night. Its an 02 ..... now it accepts my Orange Sim Card ..... but he told me that the phone is reg'd to 02

I want to put it on Orange - so I am wondering -
1. If he cancels it - will they lock it (assuming his independant Insurance will replace it)???
2. If its locked at all ?? - as I have used latest DCT4 Hollow and Cyberdog calc... and when i enter any of the codes it states code error....

Please let us know
