about a 3 week ago i bought a samsung tocco and got 3 to send me my picture messaging and internet settings. Since saturday i havent had a signal so i rang 3 who said they have now blocked all 3 sim cards from working on any none 3 phone. They wont let me cancel my contract even tho i got the letter through the post. So now im without a phone. How much would a samsung tocco with 8gb memory card thats still got everything it orginally came with be worth now?
