System requirements

Mobile phones based on the S60 3rd and 5th edition platforms are supported. You can check your S60 phone system version here. You can also find an incomplete list of supported devices in this forum topic.

S60 2nd Edition is not supported any more. You can try SymTorrent 1.30, which is the last version that was released for S60 2nd Edition. You can found old versions at the downloads page. However, please be advised that this version contains several bugs, which can result in poor performance.

Installation instructions

Before installing SymTorrent you must make sure that the "Software installation" option of the Application manager is set to "All"!

This is especially important for Nokia Eseries phones, since this option is set to the wrong value on them by default.
The Application manager can be found in either the Tools menu or the Applications menu. Start the App. manager, select Options and then Settings.

General information

Just like any other application which accesses the Internet, SymTorrent generates network traffic. You should be aware that mobile network operators usually charge for the amount of downloaded and uploaded data. SymTorrent can also generate traffic while sharing already downloaded torrents.

SymTorrent is free (and open source) software, distributed under the terms of the GNU General Public License. We highly appreciate any help. If you like this software and want to support the development of SymTorrent by making a donation, you can do so via PayPal.

SymTorrents icons

The meaning of the various icons you can see in the main view of SymTorrent are as follows. Key 1 refers to the state of the download. Key 2 shows whether the torrent is being shared or not.

Key 1
	The torrent is being downloaded. It means that SymTorrent is actively connecting to other peers and trying to request undownloaded pieces of the torrent from them. It doesn't necessarily means that there is active data transfer at the moment though.
	The transfer of an unfinished torrent is paused. SymTorrent doesn't connect to peers, download pieces or accept incoming connections for a particular torrent when it's paused. Select "Download" from the options to start downloading the torrent.
	The torrent is fully downloaded. SymTorrent will no more connect to peers or request new pieces. However, other peers may still connect to SymTorrent and request pieces which they don't have. This is called "seeding" and can only take place if the torrent is being shared and incoming connections are allowed. See Key 2 for the status of the torrent from the incoming connection point of view.
	The download of the torrent is failed. It's either ran out of peers to connect, failed to establish network connection or encountered some other problem. You can check out the exact reason at the end of the torrent properties view (select the torrent and switch the tabs until you get to the properties view then scroll downwards). You can try to resume the download via the options menu.
Key 2
	The torrent is being shared but there is no active upload at the moment. SymTorrent accepts incoming connections for the torrent and uploads data if a request arrives.
	The torrent is being shared and there is active upload at the moment. SymTorrent accepts incoming connections for the torrent and uploads data if a request arrives.
	The torrent is not being shared thus no upload can occur. SymTorrent refuses any request fot the torrent. You can share the torrent either by selecting "Download" from the options (a torrent is allways shared while being downloaded) or by the "Continue sharing" option if the torrent is already complete.

Accepting incoming connections

Since version 1.10, SymTorrent can accept incoming connections. This means that other peers can connect to your mobile phone if it has an IP address which is visible to other participants of the network. However, in most cases when you connect to the Internet through your mobile phone, you are behind some kind of router and your device isn't directly accessible to others. If you are using 3G/GPRS then you can only hope that your network operator gives you a "public IP address", but if you are, for instance, using wlan with your own router then can configure the system to forward incoming connections to your mobile phone.
As you can see the point is that accepting incoming connections on mobile phones is not so straightforward but if you have an option to configure the system then it definitely worth your effort. You'll likely get more connections thus better transfer speeds this way.
