I live in place where the data charges are extremely high (~0,70€ per MB in Ethiopia, for example.) If I wish to chat on Facebook, data charges rack up quickly due to the standard Facebook app's bandwidth use: always updating the stream, downloading all of the images and profile pictures, etc.
Is there a way to restrict or minimize bandwidth utilization while using Facebook chat, basically only transmitting the text data? 3rd-party apps would be fine as well.
PS: I already tried to download imo.im from the Google Play market - but this one is not available in Ethiopia.
