Sprint looking to raise $2B to fund LTE network

After a successful campaign in the fall which raised $4 billion, Sprint is looking to sell another $2B in company bonds via a private sale.  This money will be going towards network expansion and upgrade (LTE), as well as to possibly help fund Clearwire.  This is all part of Sprint's Network Vision plan, which will ultimately see their iDEN network shut down and their CDMA offering on both the 800 and 1900MHz frequencies.
