1101 & 6300

Hello Forum,

Got both of these and as far as I understand (pls correct me if wrong) both are DCT4 models:

1101: May be hard locked as I didn't know (hence guessed) the network (an old one from the office). Is there anything I can do if it IS hard locked and if not how can it be unlocked if I don't know which network it is locked to? Unlock.nokiafree and all others on the net require this info.

6300: Locked to Orange but unlock.nokiafree etc apparently doesn't do that. 6300 is not listed. Don't want to mess it up.

Does any one have any ideas?

Steph
