3next is a site designed to find the best, innovative mobile 3G applications. You can also vote and rate these applications.
Over time 3neXt hopes to build up a large catalogue of links to software and sites. Its a great initiative and especially coupled by fixed price mobile tariffs from Three, its practically useful as well. I would recommend that you have a look at it – both to rate applications but also to upload any interesting 3G applications you are working on
