INTERVIEW: Mark Newman, Chief Research Officer at analyst house Informa, talks about some of the latest trends affecting the mobile voice and data markets.
Speaking in advance of his address to the Insights'09 conference next month in Lisbon, he discusses the impact of the iPhone, the rush to open app stores and carriers' attitude to mobile VoIP.

Skype is now available for the iPhone - and will be coming to BlackBerry in May.
The VoIP app on the iPhone will only work over Wi-Fi and not 3G.
It will allow iPhone subscribers to use phone numbers in their existing iPhone address book - without the need for duplicate lists.
UPDATE: Since being released on Tuesday it has emerged that Skype on iPhone does works over 3G, despite being intended only for use with WiFi.

Vyke Communications has announced a beta version of its mobile VoIP software and service for all Windows Mobile 6.0 and higher based smartphones.
The solution is based on Vyke's stand-alone proprietary mobile VoIP technology, which the company claims allows it to provide high quality voice service while circumventing any operator handset tampering issues.
