Hi. I am writing in Czech using the Polish keyboard. Hopefully there will be a Czech localization (and others more), since there is no obstacle from Linux to support almost any language you want to.
I never tried it on Vipnet, only on HT/T-Mobile, but I believe there should not be a reason not to work. I have private Tomato SIM card, I can try it if you wish.
Note about keyboard: for diacritics (for example "ć"), you must long-press key "c", and then you get options like "č" and "ć".
And thanks again, it was a very useful piece of info.... I've actually ordered my Jolla half an hour ago:)
Well, I also believe there shouldn't be any reason for Jolla not to work on Vipnet. But, since you mentioned it, yes, please try that Tomato sim card - I have a couple of friends very interested in buying Jolla, and some of them are on the Tomato network.
Thanks also for the keyboard tip; so it actually works the same way as on BlackBerry 10 (I've never used any other mobile platform) and I like it that way.
Nice to know there are other Jollas in Croatia:)
Ps.: I'll be back with more questions once my Jolla arrives...:)
