I found the coverage of

http://www.inandphone.ch/ , the 5th swiss network - in Lausanne, Vevey and Geneva
Now I'm waiting for their first prepaid offer :P
Also I didn't find <span style='color:red'>
Tele2</span> network in Lausanne and Geneva... they said that - after Zurich - will cover Lausanne, Bern, Geneva and Basel in 2006. I'm waiting for them :construction:
