It seems odd that you think an upgrade of the OS will resolve what is probably a GPE bug.

Given the length of QA, sign-off and planning that goes into a commercial software release you'd only see a rushed out firmware if there was a major bug. Nokia don't "release often, release early" - they, like many other software houses, release "when it's ready" (dependent on marketing).

OS2008 will get better and evolve, just as OS2005, OS2006 and OS2007 did.
