Can I change oprator logo by Fexplorer?
It seems better ....

Yes, with FExplorer it's pretty easy, just highlight the image you want, go to Options, File and finally Set as operator logo.
Hope this help.

It doesn't work if you are on the stupid 3 network! :(

Here Is Oprator Logo.
C:/system/appl/phone/oplog/put Your Photo.

I Think It Will Work Good.
