Sprint is slated to announce its Q2 2010 earnings on Wednesday and analysts are weighing in on the expected performance of the nation’s #3 wireless carrier. Though it is still losing customers to its competition, Sprint is expected to show improvement year over year in the important postpaid category, with the carrier losing approximately 425,000 customers in Q2 2010 as compared to the 991,000 loss reported in the same quarter last year. Analyst Brett Feldman of Deutsche Bank notes that part of this improved performance can be attributed to sales of the HTC EVO 4G, which lowered subscriber loss by 100,000 and potentially kept this important financial figure under the half million mark. These numbers would have been better had Sprint been able to meet customer demand for the EVO 4G, but constant shortages have plagued this 4G handset. With the Samsung EPIC 4G slated to drop later this year and, hopefully, the EVO 4G back on the shelves, Sprint’s upcoming performance in the growing 4G postpaid market looks promising. Do you agree?
