Mobile image cache size limitations?

Is anyone familiar with a comprehensive list of mobile devices and their browser's cache limits f开发者_StackOverflow社区or images?

I found one reference for iPhone:

But it's 3 years old. It does state, however, that the iPhone won't cache images over 25k.

I'd like to know if that's still true and if anyone has similar info for Nokia, BlackBerry and Android devices.

The only posts I could figure out (by searching on Google) are the following:
