HTC TyTN II

HTC TyTN II with Yandex.Maps running

Software

SSH

I found only one SSH client which works well. It's Token2Shell/Mobile v. 5.2.1.

Maps/GPS

Google Maps is a must have for walking on various wild places because its satellite pictures.

Yandex.Maps is a must have for big cities of Russia. Shows addresses and traffic jams very well.

I also found City Guide's maps usable for Krasnodar Krai.

Book reader

AlReader2 becomes a great thing for me.

Hardware

Something you can found on dx.com:

I highly recommend to buy an extended battery pack. Wonderful thing. With this you are just start feeling pocket computer in your hands, not a rattle for a hour of intense usage.

Never buy this battery, because it just doesn't work. I had to ask dx support for replacement for defective item (and they did so).
