Users of O2's Active service are able to access eBay using their mobile phones for the first time today.
O2 Active subscribers can login to the auction site, search, bid, and keep an eye on items they are selling or considering bidding for.
eBay has been available on i-mode since January this year, but will now be accessible through the main O2 mobile portal.
O2 general manager of content Simon Dean said: "Our experience with eBay on i-mode has shown us there is a really strong demand for it from our customers who really want to engage with these types of services." ®
