Problem in Xperia X10
 

dear all ,
i need any help, i face a problem with Xperia X10
in the phonebook i saved the contact like this (0111144926) . but when i receive sms or mms i receive it from the same number but in a different format like this (+20111144926) so i can't notice who is the sender of this sms unless i checked the phonebook.
so any help please...
i want to change the setting of the messaging to be i a same format like the phonebook.
thanks for support...
