Sprint Nextel will go forward with its plan to shift push-to-talk subscribers off the iDEN network and onto a CDMA-based network in the fourth quarter. The CDMA network will cover a much larger area than the iDEN network and will have more bandwidth to help boost coverage across several frequency bands.
Sprint Nextel intends to roll out new handsets and features for its iDEN customers, saying it will continue to support the push-to-talk service at least until 2012. The carrier's iDEN customer base stood at 18.7 million at the end of the third quarter of 2007.

About 15% of American cell-phone users make use of the Web-browsing feature on their phones, according to M:Metrics.
Netgear and Thomson each unveiled new dual-mode phones that enable service delivery using Skype's VoIP as well as a landline. Each new phone makes use of the Digital Enhanced Cordless Communications cordless phone standard.
