Ok I've done this before, many times I've fixed people's accounts. You can ask cereal if u want, i fixed his account long ago...
What you need to do is find a corner in your house or somewhere far from your house that has a laggy/low connection. Example: Your basement, or try going outside of your house but not too far, as you don't want to lose the connection. You can test the connection % from your psp too. What you want is around 33%-50% if i remember right. Log on real quick -> go to your cell and disband before you freeze. Viola!.
