Update 2011-12
I left my sweet dreams about open source mobile phone for some time.
Since Nokia N900 was released I was its happy user (and I'm still using it) but I came to conclusion that mobile phone is better not to be a same device as mini-notebook or camera or anything fragile and hungry for battery.
I end up buying tough Sonim XP3 to use it as phone only so I'm charging it only once a week and have no worries about losing connectivity due to lack of charge or wet weather or whatever.
- Apple iPhone? You must be kidding.
- Windows Phone 7? Come on, Microsoft incompatible with ethics.
- Android? No, thanks.
- Perhaps Nokia's Maemo? Probably not, after their alliance with Microsoft.
Openmoko FreeRunner - yes, that's the one.
