300 is a far stretch for me. I would think that if indeed we see another leak it would be more along the lines in the 240's or 250's. But thst of course is my opinion. I'm going with what my friend Olta says on this one.
Same here there is no 300 build for storm, next leak might be the one jumping the app version to 5.x, that's why things like threaded sms is buggy on the storm but not on the devices running OS 5.0 with the apps ver 5.x
