People looking to track their eBay auctions when they are away from their computer will be able to do so via their mobile phone.
O2 has partnered with the online auction house to offer the service as part of its i-mode network offering.
Available in the UK from today, the service allows customers to bid for goods but not sell them via an O2 mobile phone on the service.
They will also be able to view all of their familiar "My eBay" features, including "items I am watching", "items I am bidding on", "items I am selling" and "items I have won".
eBay becomes the 126th i-mode site, and joins internet sites such as Monster.com, Egg, Rightmove.co.uk, Universal and Interflora.
i-mode was originally developed by NTT DoCoMo, Japan's largest mobile operator, and has attracted 50 million users in 22 countries since its launch 6 years ago.
