The giffgaff virtual mobile network operation, which runs on O2’s UK network, has introduced BlackBerry services today.

There’s now a ‘goodybag’ tariff option that enables customers to use a full range of BlackBerry services, including BlackBerry Messenger and ‘push’ email, for an additional £3 per month.

This week’s podcast from The Fonecast starts with impressive quarterly results from Apple, along with figures from Samsung, Motorola and Nokia as well. We then move on to some of the other stories that have been hitting the headlines, including O2’s UK privacy problem and a new ‘unlimited internet’ tariff from T-Mobile.

As usual, you can listen to this week’s podcast on our website audio player, via iTunes, by using our RSS feed or by downloading the MP3.

Apple, Samsung and Motorola have all published their quarterly results. We talk about these differing figures before moving on to O2's privacy problem, T-Mobile's new unlimited tariff, HP's plans for webOS and last year's growth in tablet sales.

T-Mobile UK has announced a new tariff that’ll let customers make unlimited calls, send unlimited texts, and use the mobile internet as much as they want without any ‘fair use’ restrictions.

The deal is called The Full Monty and will be available on all phones in the T-Mobile UK range from Wednesday 1st February 2012.

The Carphone Warehouse Group plc has published an interim management statement for the third quarter of its current financial year.

It says its business in Europe performed strongly on post-pay (‘pay monthly’ deals) and non-cellular products, although a weakness in the lower-value prepay market resulted in like-for-like revenue being down by 4.7% when compared with the previous year. Overall, figures for the full year are expected to be in line with previous guidance.
