There are as many as four different view modes available for the main menu of Nokia 6600 fold: a grid of icons with or without labels, a list of items, and tabs. Our personal favorite remains the classical grid of 3 x 3 icons with legends. If you prefer more icons to appear on screen, you can go for the grid view without labels, as it displays a 4 x 3 icon grid.
The background color of the entire menu, as well as the wallpaper, can also be easily modified by changing the active theme. There are four themes preinstalled on the Nokia 6600 fold and downloading new ones is no problem at all.
The phonebook of Nokia 6600 fold stores up to 2000 contacts. Entries are ordered by first or last name and, quite naturally, you can find a contact by gradually typing the desired name.
There are three available view modes for your contact list: List-of-Names, Name-and-Number and Name-and-Picture. The phonebook can display the SIM card contacts, the phone memory contacts or both at the same time.
Each contact can be assigned a variety of fields but the phone numbers are limited to 5. Personal ringtones can be assigned to each contact. Naturally, you can also assign a picture or a video that will run on an incoming call. Bear in mind that the caller image is different for incoming and outgoing calls. It fills the screen when you are on the receiving end of a call, and appears much smaller when you are calling one of your contacts.
The phonebook font size can also be modified, should this be necessary, and it's an option that will surely be widely appreciated. And lastly, contact grouping is also available. This means that contacts can be organized in groups to use as call filters.
Another application to mention here is voice dial: no pre-recording of contact labels is necessary.
The Call Log in Nokia 6600 fold hasn't undergone any significant changes either compared to other S40 devices. It can display Dialed, Received and Missed calls separately, as well as in bulk. Every tab can hold up to 20 call records with their date, time and duration.
