We have upgraded a bunch of 6230's and 7230's to 4.0, and we are seeing many of them dropping to below 1MB or even having 0KB File Free memory on the flash. We are using a couple 3rd party apps such as SecurID and METAmessage.

Anybody else seeing this lack of memory on upgrades? We are considering restricting 4.0 to the 32MB devices exclusively in order to not have the device start deleting mail / calendar entries to free up space.

Thoughts?

we have started making 4.0 optional for those who have 16MB devices and pushing those who do not have them to set up purchase order requests for an upgrade to a 32MB device (we've got a pretty sweet upgrade price to the 7290 device). i have seen quite the number of issues on the 16MB devices after upgrading to OS 4.0, considering the OS takes up about 80-90% of all free memory by default (with the bells and whistles installed). this is without the use of 3rd party applications, so i can only imagine what it'd be like with those.
