Have been using twitter for a while now, and was annoyed by the tinyurls being useless on my mobile. So, I thought; how hard can it be? and made this one: mtny.mobi
mtny.mobi works as all other tiny url creators, but this has a mobile touch to it.
You can specify if the target url supports mobile when you submit it, and if you are accessing a shortened url by your mobile, you get the option of viewing the page using mowser or go directly to the target link.
Hope this will be useful for someone 🙂
