A variety of factors could cause actual results to differ materially from those anticipated in iPCS’s forward-looking statements, including the following factors: (1) iPCS’s dependence on its affiliation with Sprint; (2) the final outcome of iPCS’s litigation against Sprint concerning the Sprint/Nextel merger and the scope of iPCS’s exclusivity, including with respect to Sprint’s proposed WiMAX transaction with Clearwire; (3) changes in Sprint’s affiliation strategy as a result of the Sprint/Nextel merger and Sprint’s acquisition of all but three Sprint Affiliates of Sprint Nextel; (4) changes in Sprint’s ability to devote as much of its personnel and resources to the remaining three Sprint Affiliates of Sprint Nextel; (5) changes in iPCS’s customer default rates and increases in bad debt expense; (6) changes or advances in technology; (7) changes in Sprint’s national service plans, products and services or its fee structure with iPCS; (8) declines in the relationship between roaming revenue iPCS receives and roaming expense iPCS pays; (9) the impact on iPCS’s business of the recent amendments to iPCS’s affiliation agreements with Sprint; (10) iPCS’s reliance on the timeliness, accuracy and sufficiency of financial and other data and information received from Sprint; (11) difficulties in network construction, expansion and upgrades; (12) increased competition in iPCS’s markets; (13) iPCS’s dependence on independent third parties for a sizable percentage of its sales; (14) the inability to open the number of new stores and to expand the co-dealer network as planned; and (15) the depth and duration of the economic downturn in the United States. For a detailed discussion of these and other cautionary statements and factors that could cause actual results to differ from iPCS’s forward-looking statements, please refer to iPCS’s filings with the SEC, especially in the “risk factors” section of the Annual Report on Form 10-K for the fiscal year ended December 31, 2007, our Form 10Q for the quarter ended March 31, 2008 and in any subsequent filings with the SEC.
