In the US I remember there was some variation between carriers on how locked down the devices were–my Motorola SLVR on Cingular circa 2005 ran the standard Motorola system and I had a bunch of Java games on it and could browse WAP sites for more. I was also able to install wallpapers and any MP3 clip from my computer as a ringtone. My friends who had RAZRs on Verizon, however, had some kind of crippled Verizon OS that forced you to use their store and were less customizable. They did have T9 predictive text, though, which I was jealous of.
