How to announce launch of mobile version (Native apps + website) of a website
What is best way to inform to user of desktop website that now website have Mobile version of website and native apps for many platforms?
A permanent section on website to tell about it with icons.
or
A pop on homepage load in lightbox?
or
top floated bar with close x button?
or
A separate page and link for that in footer like http://www.flickr.com/mobile
Edit
Note: I think it's my mistake my question was not clear. My question is not only for Mobile website it's also for Native apps.
Flicker.com has a link in footer which take us a page where are links avaialbe for all apps
See this Example : http://www.flickr.com/mobile
Basecamp also do the same but they have a link at top nav http://basecamphq.com/
tripadvisor too http://www.tripadvisor.in/MobileApps
And http://www.cleartrip.com/mobile/ made a separate page for mobile and given link in footer
