Just want to give my hints, can't find any other place and hope Jolla will read here.

Want to have a replacement for my old Nokia E61i, so my better choice is to have the same app/feature I can find there

- calendar with integrated appointments and tasks
- notes with the ability of sort by creation date and extract phone numbers
- from the phone side a good conf call and speakerphone, really useful for business usage
- generic SIP client
- gps and maps (I've TomTom installed, but any with turn by turn navigation will be ok)
- the "home" screen need to be able to display today activities such as appointments or tasks
- morning alarm that can work also with shutdown mobile
- ability to easy turn on and off connections such as wifi
- contacts with many contacts details and the ability to import from Nokia format
- integrated messaging for SMS/email from many different mailboxes, such as exchange, IMAP, POP3
- VoIP such as Skype, GTalk, Whatsapp

E series was perfect for business usage, never find a replacement apart from BB but after testing q10 I finished using my old Nokia.
