I did something really stupid, or at least I think I did.

I am currently filing for bankruptcy, Chapter 7 to be exact and I filled before the October 15th deadline so the old laws apply to me. Due to everyone filing at the same time my court date is scheduled for sometime in December. I just today applied for a cellphone and I was approved and now have it. Is this going to look negative when I go to court? Is this grounds for them dismissing my case? I needed a cell phone because I live in a terrible neighborhood (I can't afford to move) and don't get home until after dark and I feel safer carrying one. I also need it for work (in case they need to contact me and vice versa) and sometimes transportation reasons. Please lend me your knowledge in regards to this!
By the way, I do also have a house phone which I was planning to turn off now that I have the cell phone so it would become my main source of contact.

Thank You!
