My Sony Ericsson W580i, has been cloned.

How would I go about uncloneing my Sony Ericsson W580i? Unfortunately, I let someone I thought I could trust, use my cell phone. Now, not only my calls but also my text are being sent to not only my phone. But, to another one also.I dont understand how to do this. So, I cannot get it Stopped. I never fully understood the need for security on my cell phone, until now.Gosh, I feel so stupid. Please, Help Me...

Wow... how is that even possible?

yes, how is that possible

okay i think i can help....

go to menu, settings, calls

then there should be a tab called redirect or call divert,

and in that category there should be a number that it is redirecting>delete it and your back to go

or call up the number asnd hunt down the person

>=) lol tell me if that solves it!!
