Lots of buzz around for VoIP on 3G network , here is the exclusive review from msmobiles.com

Skype for Pocket PC in latest version brings even more features of the Skype for PC, although still Skype video calling is not available (although it would be possible due to availability of camera API in Windows Mobile 5.0).

Furthermore to make voice calls with Skype one doesn’t have to have access to Wi-Fi and making voice calls is possible and feasible also over cellular networks! It is pity, that Skype for MS Smartphone is not yet officially available - clearly the reason was lack of MS Smartphone devices with powerful enough processor - but since both Motorola Q and Samsung SGH-i320 already have powerful enough processors it could change if only Skype would be willing to put some effort into it.

Anyway the version of Skype for Pocket PC is a very mature one, particularly in the latest version that we have tested here, and since still there is no Skype for Symbian, it is also a very good reason to buy Windows Mobile phone… if you don’t have one yet!

Also, Tom Keating from TMCnet has a review on latest Skype for Pocket PC 2.1 Beta.

Nokia is pushing to popularize UMA (Unlicensed Mobile Access) technology in the mass market. The global mobile phone giant is putting the resourcesis to trial its first voice-over-wireless LAN system and service in Finland which will allow mobile users to make use of lower cost voice calls over the Internet.

The system, called Unlicensed Mobile Access (UMA), is being tested by 50 households in the city of Oulu. They are using the Nokia 6136 handset which is among the first mobile phones to support the handover of voice and data calls between a WLAN and the local GSM network.

The users will be able to roam and handover between local area networks and wide area networks using the same dual-mode handset.

The handset does not need to continuously communicate with a GSM basestation, but will also make calls through WLAN Internet networks. Which opens up the use of lower cost voice-over-Internet protocol (VoIP) services.

UMA technology makes it possible for users to seamlessly roam and handover between local area networks and wide area networks using the same dual-mode device. Instead of constantly communicating with a base station, UMA allows the phone to also make calls through WLAN internet networks. In turn, this will also make it easier and cheaper for operators to expand their area coverage by implementing WLAN hotspots instead of costly base stations.
