text: **Higher Handset Subsidies**
  is based substantially on subsidizing the 
  Our wireless business model 
  cost of subscriber handsets, similar to other North American wireless 
  carriers. This attracts customers and in exchange they commit to a term 
  with us. We also commit to a minimum subsidy with the supplier of 
  certain smartphone devices. 
  
  BUSINESS RISKS 
  
  **Revenue Expectations from New and Advanced Services**
  We expect that a substantial portion of our future revenue growth may 
  come from new and advanced services, and we continue to invest 
  significant capital resources to develop our networks so we can offer 
  these services. It is possible, however, that there may not be sufficient 
  consumer demand, or that we may not anticipate or satisfy demand for 
  certain products and services, or be able to offer or market these new 
  products and services successfully to subscribers. If we do not attract 
  subscribers to new products and services profitably or keep pace with 
  changing consumer preferences, we could experience slower revenue 
  growth and increased churn. This could have a materially adverse effect 
  on our business, results of operations and financial condition. 
  
  **National Wireless Tower Policy**
  The policy affects all parties that plan to install or modify an antenna 
  system, including PCS, cellular and broadcasting service providers. The 
  policy requires, among other things, that antenna proponents consider 
  using existing antenna structures before proposing new structures and 
  those owners of existing systems respond to requests to share antenna 
  systems. Antenna proponents must 
  follow a defined process for 
  notifying the public and addressing local requirements and concerns.
