LTe T-Mobile Netherlands

The first 3 days my G4 showed a 4G icon on top. Everything whas installed and then all of a sudden a 3G icon appears at the bar. Checking the setting it shows i only can connect to 2 and 3G. This puzzles me.
At T-mobile they told me that the phone wasnt a 4G phone, so i showed them the specs, then they said in the netherlands 4G was only on the 2100GHz band. Googling i found out that it should also work at the 1800GHz band.

Band 1: 2100 MHz
Band 3: 1800 MHz
Band 8: 900 MHz
Band 38: 2600 MHz

So i wonder, has any one set up 4G Tte T-mobile in the netherlands with the Gemini and how to do that?

Thanks for reading this...a complete noob

Android/Linux etc.

Ok i dont have my machine yet, but i'm reading the posts here and i get confused coss its not clear to me when the post is about Linux or Android (sometimes i do). I dont know anything about Linux and i'm not planning to use it, so i'm only interested in Android. So is there a department on this forum that specificly talks about Android and nothing else?

For me that would be most usefull, and perhaps for others to.

Thanks....

Screen to keyboard connection

Ok so i probably overlooked it but how is the keyboard connected to the screen. My Mx5 died when the cable broke, so its good to know what to expect.
