What has been the feedback from upgrading your Apache to the AKU2.2 upgrade.

So far i have done 4 devices,

1 x unit kept loosing email accounts after upgrade so we serviced and reverted back to original firmware - works fine now.
2 x upgraded and the crashing, locking up bugs have gone or are less prevalent, coverage seems better and EVDO signal seems to be obtained further from the site? Also recieves calls more often than did before!

My unit has been upgraded, it seems a little sluggish (all units i have done seem this way) but the phone works better, my mp3 ring tones don't always take half the ring time to start ringing, the EVDO coverage or ability to recieve EVDO seems to be much better.

What results have others had?

I have several clients with mutliple Apaches, all crashing and locking up and not perfoming  or recieving calls on the old version, has any one else had this problems?

I have also been getting the comments from this client that the Imate versions or similar devices are stable and reliable yet the Apache seems to be unstable?

Your thoughts?
