Hi All Gurus

Can you help me out here please..

I have a VF Nokia 6500s and i have switched to XT now, it is working fine
 
How do i get rid of the VODA logo in the menu where we click to go to WAP? and how do get the T World short cut instead of the Voda ?

I have changed settings of internet so it is using XT wap access, if i click on VF logo it goes to XT wap portal ...

i want to get rid of VF logo from menu.. Is that even possible ?
