Arrgh! I need more help please!

Hey, before you read this it's about 2 BBs so I had no idea where to put it... Hope this is OK.

Yesterday I posted some threads about getting a Pearl on a UK PAYG network, my plan is to sell my PS3 and some games and I was going to buy the 8120 from Orange.

But, at CeX (Computer Exchange, store in the UK) they have a Pearl Flip on Orange for �180, and I get �176 + �6 for just my PS3 and 1 game. Another thing making me unsure is that it's a Grade B. But I'm guessing it shouldn't be too bad.

I already have an Orange SIM as I used to be with Orange and I've read that all you need to do is put in any SIM, ring up Orange and request for BIS.

OK. maybe I'm missing something. What do you need help with? You are correct with the SIM card.
