<div>The [[Nokia N900|N900]], unlike previous Nokia internet tablets has a phone module.<br />
<br />
==Hardware==<br />
<br />
The phone is a 2G/3G modem, with quadband GSM, and several bands of 3G. It may not have the required band for 3G in your country, for example, only one US carrier (T-Mobile) and only one Canadian carrier (Wind Mobile) support 3G on the N900.<br />
<br />
The phone module controls the [[N900 Hardware GPS|GPS]], and contains software to generate locations.<br />
<br />
==Software==<br />
<br />
For the GPS, [http://maemo.org/api_refs/5.0/5.0-final/liblocation/ liblocation] is used.<br />
<br />
The modem can be accessed 'directly' - through pnatd.<br />
<br />
[http://www.gossamer-threads.com/lists/maemo/developers/59363 This thread on the maemo-developer] mailing list gives some examples of using pnatd - but it is not a reference guide.<br />
<br />
[[Documentation/Maemo_5_Developer_Guide/Using_Connectivity_Components/Maemo_Connectivity#Internet_Access|ICD]] is the daemon that deals with internet connectivity, including managing data connections to the phone.<br />
<br />
More documentation on ICD is [http://maemo.org/api_refs/5.0/5.0-final/icd2/ found here].<br />

SMSs are stored using [http://maemo.org/api_refs/5.0/5.0-final/eventlogger/ eventlogger]<br />
