i hope this will help you .

If you have unlocked your mobile it will not show O2. Contact your network provider to check it. If it is not unlocked properly you can try to unlock it again. Unlock codes are also available online like www.theunlockspot.com.

Check that your o2 number is activated and in-service by using it on another handset or just call the o2 helpdesk to get your number activated if it is a new service,
If you can assess that your new o2 number is in service and the HTC Touch still does not work, then your handset has not been fully unlock as they are basically two types of locks:
1) The 'normal' Network lock that allows any 'Orange' SIMs to work on the device (basically unlocked by NUK code)
2) The 'nasty' SIM lock' that only allows a SINGLE number on a specific SIM card to work on the locked device.
In either cases, make sure that you get all restriction lifted.

Hope it helps: let me know how you go and good luck!
