I have a cell phone and it's about to bite the dust. Its a Rogers Samsung D807 with a SIM card inserted. There's someone selling a Fido LG Neon, now if I were to buy it, would I be able to use the Rogers SIM card that is inserted in my current phone? I just got my phone a month ago for free from my buddy, and then I bought the SIM and paid the activation fees which wasn't too cheap... I don't want to have to pay again and I don't want to pay around 200 bucks for a new phone. Normally I wouldn't care but my parents are too cheap to buy me a phone themselves and pay for a plan so I have to pay for the whole thing myself. Any help / knowledge on locking / unlocking phones and that sort of thing is greatly appreciated. Thanks
