Vodafone has revamped its Twitter offering with a new option that allows customers to retweet friends’ posts using SMS messaging.

Up until now Vodafone customers could send and receive SMS Twitter updates, however the new service now lets them retweet posts using the same number.

In order to take advantage of the additional application, consumers are simply required to send an SMS using the format "RT twitter username" to 86444’. They will receive a email from the carrier to confirm that it is active.

Vodafone’s move comes after Orange this week announced a partnership with Twitter than will allow customers to upload and share photographs on the micro-blogging service via SMS.

The venture will also see Twitter incorporated into Orange’s Social Life mobile networking aggregator.

This effectively brings all people’s social networking profiles and activity into a single location and according to Orange allows “fast and simple access to Twitter without the need to download special software or pay extra for services”.
