Iphone… usefull apps

After having a Blackberry for years, I finally got the possibility to choose… an iphone5

• Today I got a nice link from @Nico_Broos about a review of the Google Nexus 4 which shows things that were obvious to some of us : http://www.anandtech.com/show/6440/google-nexus-4-review/3

Apps I installed extra :

• Evernote
• Google Maps
• Tweetcaster
• Skype
• Flashlight

Things I’m missing as a free app:

• Email advanced alerting (e.g. a custom ringtone when a mail with a specific subject arrives )
