I purchased an unlocked iPhone on eBay. I placed a sim card in the phone and it immediately goes to searching then it shows 5 dash lines. I tried several different sim cards even one out of a co-workers iPhone, still the same result.

I have tried Ziphone and iLiberty, after running the programs I end up with the same results. Can someone tell me what the problem and solution is?

Please make it as simple as possible, I am kind of new to this unlocking stuff.
