IPCS Adds 7,800 Net Subscribers in 4Q

The company ended December with 629,900 customers. Its average monthly churn, or subscriber turnover, was 2.7 percent.

IPCS said the subscriber growth through its Sprint-controlled and national channels "continued to be weak," which led to lower-than-expected subscriber growth.

Last week, Sprint Nextel Corp. reported fourth-quarter subscriber numbers well below Wall Street's expectations, and said it will slash 4,000 jobs to cut costs. The beleaguered wireless carrier's stock lost nearly a quarter of its value following the announcement.

IPCS sells wireless products and services under the Sprint brand in 80 markets, including Illinois, Michigan and Pennsylvania.
