Today I bought a new SIM at different operator, mainly because of better network in country side. So, N900 chooses to go for 2.5G instead of 3G or 3.5G(which my old sim was doing). My friend has the same type of sim and his phone chooses 3G, not 2.5G like mine does. I called the help line and they said that few phones have manually changable which to use (3G, 2G......), and this feature, as i understand, N900 doesn't have ( not that I needed it with my old card). With this SIM i'm gettings average 10-20kb/s download speed, with old one - 100kb/s was the lowest. At nights - 150kb/s average.

So, isn't there any way i can make it to connect to 3g?

btw, offtopic question. Does my warranty provider has to change my phone if the touch screen makes strange noise, almost like when pressing keyboard, or maybe... like "click" ( only when touching arond the clock and that area, and that really is the screen it self what makes that sound) and i REALLY hate when it makes that sound. Do they have to change my phone? It's not always, 30% of the time it doesnt do that.

it's local phone shop's warranty.
