Here's a couple of ISS photo's I took late last year, October and December 2013, using my Samsung Galaxy S3. 1st one was done with a 10 sec exposure and the 2nd was 20 sec. I used an app on Android called Camera FV-5 which allows you to do up to 60 sec and it's free. I know there is one for the iphone called shutter cam (I think). ISS evening passes start again 6th April. You can find times and where to look on Heavens Above. There is a link to the site on the right hand side under my fav sites.
