SymTorrent is the first full-featured and complete BitTorrent client for Symbian OS. It supports downloading multiple torrent files at the same time, is capable of both downloading and uploading and can save the status of your unfinished torrents, so you can resume the downloads after restarting the application. You can also check the status of each file inside a torrent along with several other statistics and properties during download.

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 Symella by making a donation, you can do so via PayPal.
System requirements

Mobile phones based on the S60 2nd and 3rd edition platforms are supported. You can find an incomplete list of supported devices in this forum topic.
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.
Installation

SymTorrent is a self-signed application, which means it hasn't been sent to Symbian for testing. Before installation you should make sure your phone has the "Software installation" option of the Application manager set to "All" (Tools / App. mgr. / Settings), otherwise the phone may refuse to install the application.

Due to the self-signed certificate, you will see some warning screens during the installation process, and therefore will have to select "Continue" several times to proceed.

SymTorrent 1.12 is released. I've fixed an ugly bug which caused a crash on some older S60 2nd edition devices when the user entered the "Details view".
From now on, autostarting SymTorrent works on 2nd edition devices (.torrent file extension is associated with SymTorrent). You can select a .torrent file in your browser or file manager and the application is started automatically. This feature is still not supported on 3rd edition devices due to the strict security restrictions.
Please check out this forum topic and post a reply if you are using SymTorrent on a type of mobile phone which isn't included in the list.

SymTorrent 1.10 is released. The new version can accept incoming connections (please read the notes on the about page) and besides S60 3rd edition, S60 2nd phones are supported too.
The binary (installable) version of SymTorrent 1.0 has been downloaded over 1700 times till now.

Some of you have reported that SymTorrent doesn't reload the torrents after a crash. This is because in the current version the state of the torrents are saved only if you exit the application manually. It means that if the application crashes, the state of the torrents won't be saved at all. In the next version, SymTorrent will save state in every X minutes so you will only lose the data downloaded in the last X minutes.
Accepting incoming conections is also a missing feature, it will be added in one of the upcoming versions (SymTorrent currently uploads data only if one of the peers you are connected to requests a part).

The first version of SymTorrent is available for download. It has been under development since the beginnning of 2006. We have tested it on Nokia N80 and N91 smartphones but it can still contain some untracked bugs, so any feedback is appreciated. We are going to add a forum to the website later but you can contact me directly.
