I still have the original 2g iPhone and I am up for a full upgrade discount for the 3gS on August 19th if I sign a new 2 year contract. Here is my concern though. I am in the process of buying my first home and have been told not to have any credit inquiries for the next month or so. I have no problem signing a new contract but I don't want AT&T to run my credit again. I signed up for service back in March of 2007 and they ran my credit at that time and of course I had no problems. My question is will they run my credit again just to extend my contract by 2 years? Any information that could be provided would be appreciated. Thanks.
