Turned out that it had been flashed to 6.5 by Sprint. hardware ver 4 and apparently only 3-4 months old. Seems quite zippy. My only complaint is that apparently they changed the task mgr and you can no longer specify to close things if you click on the X, but I am also noticing that it doesn't seem to bog it down to have a few things sitting in there. Found a killer app FdcSoft_TaskMgrv3.3_WM6.5.cab in an attempt to replace Seligman's Launcher (worked in 6.1, no go in 6.5) - does everything including a regedit. (Fred dot, I think)(have to power off and on for it to be found)
I also found that location in google maps works fine on the Rhodium, where it didn't on the Mogul. (course it's within 900 meters so really useful!!!
But fun!
I haven't gotten around to trying the froyo 2.2 yet (Android) - prolly tomorrow. All-in-all, very pleased with this new toy, even though I haven't found the "serve espresso" button.
Going "slowly - just want to make sure it doesn't have a terminal sleep prob - speaking of which, my mogul occasionally did, so for fun last night I did 3 clear memories. Good thing to have up one's sleeve if problems arise!
