allthough it is a half baked month old beta release of pr 1.2 ive found that

*battery is better through 1st day
*rootfs is much improoved
*can hold button to get blue symbol on qwerty pad
*streaming off large divx/avi files now works again
*gps signal seems to lock on quicker
*extra camera and video options
*new virtual keyboard layout
*nokia maps has seen slight improovements
*auto portrait for the browser
*no more ''more'' in the main menu
*video chat via skype/googletalk etc
*slight web browser speed increase
*web browser ui improovements with back button etc
*mynokia service now built into n900 for tips via sms like s60
*send many types of file via bluetooth without petrovich
*sms and missed call alerts on the swipe to unlock screen
*quite a few other slight improovements which add up nicely

so far even though its a beta release it hasnt caused my handset any problems yet and that is a big yet

i wouldnt recomend any user to flash this early beta release at all and i only done so as i have insurance on my n900 and love to mess around with my gadgets etc it has caused alot of users troubles and users should really wait for the offical pr 1.2 release where any of these bugs should hopefully be ironed out

as other users have sad if this release was good enough it would have been released by now on the servers it was obvously held back for a good reason and some users are finding this out

from the early beta that has been leaked though , pr1.2 should be really good and i hope it hits the servers soon
