6610 locked by USA t-zone

My phone cannot receive internet settings for O2 as I have tried several times. When the settings are sent and I try to save them the phone says the memory is full. This is not the case I have plenty of memory free. can any one help me in this matter. In the services menu I have t-zone and it is locked there so I can not delete it.? Has anyone seen this befroe and can it be fixed? At the momement the phone is running O2 fine but I cannot access the GRPS or WAP.

My serial# is 350893309447203
Thanks for your help in this matter.

then you will be able to save the new setting
on your fone
