Islamic militants in Pakistan's tribal areas, which border Afghanistan have issued a decree banning music from mobile phone ringtones and vehicles in tribal areas of the country. A spokesman for the Tehreek-e-Taliban Pakistan, Maulana Faqir Mohammed said, the they would not allow commuters to play music in their cars or use musical ringtones on mobile phones.

He warned that offenders would be punished according to Shariah lynch mob law.

This is not the first time that Taliban leaders have tried to clamp down on music in their areas - and a wave of attacks on mobile phone stores in North Waziristan was carried out last October to stop them selling music capable phones.

The shop-owners said at the time that they had received several letters, asking them not to sell mobile phones pre-loaded with 'musical' ring tones. Many retailers had started offering phones pre-loaded with 'jihadi' ringtones, but this did not seem enough to appease the militants.

T-Mobile and Orange are to run a commercial trial in west London of a new mobile TV technology which could allow handset users to tune in to up to 100 channels.

The technology, TDTV, has been developed by US-based NextWave Wireless and could provide a cheaper and more efficient way to get broadcast TV on to mobile phones. The trial, due to start in late summer, will see several thousand Londoners given either a new handset or a wireless receiver, no bigger than a matchbox, which will transfer the channels to their mobile phones.

The six-month test will see Orange and T-Mobile share their masts in London and install equipment that will allow them to broadcast 24 high-quality TV channels including several from the BBC and BSkyB, and 10 digital radio stations.

TDTV uses a slice of the 3G spectrum which Britain's five networks spent £22.5bn buying eight years ago and which has so far lain dormant. As a result, TDTV works with the phone companies' systems, making it easy to bill customers.

TDTV is more efficient and has more capacity for channels than other mobile TV solutions. Orange, T-Mobile, Vodafone and 3 are all offering mobile TV through their 3G networks but they suffer from congestion if more than a handful of customers use the service in the same place. TDTV uses a different part of the 3G spectrum and many more users can watch TV simultaneously.
