From the myriad of January sales out there we thought we'd pick out O2's effort, which has offers on PAYG and pay monthly phones as well as a few discounts on phone related accessories.

There seems to be a decent choice so we thought in the interest of efficiency we'd give you the full list, as well as this link to the store locator which also has telephone numbers so you can make sure the transportable telephone you want is in stock.
