In the fourth quarter, data service revenues increased 66%, compared to the year-ago period and 14% sequentially. The growth is being driven by strong take rates for Power Vision SM data services on handsets, demand for text messaging and increasing laptop aircard usage supported by EVDO expansion on the CDMA network. Data contributed $8.75 to overall post-paid ARPU in the quarter and reached nearly $12 of contribution, or 20% of CDMA postpaid ARPU.

Overall ARPU was a little over $60, reflecting a 1% sequential decline and a less than 5% decline from the year-ago period. Post-paid ARPU continues to be impacted by lower voice revenues, which are being partially offset by growth in data revenues. Sequentially, CDMA ARPU was flat at $59, while iDEN ARPU declined 2% to $62. Compared to the year-ago period, CDMA ARPU was down 1%, while iDEN ARPU declined 8%.
