I tried searching this but couldnt find any help.

two questions:

1st) Is it possible to use 2blackberries(7290 and 7105t) on one dekstop manager?

2nd) when you load the latest 0S 4.1, does the Desktop manager recognize which OS belongs to the appropriate handheld?

1. If you are using e-mail redirection it will screw things up since it will want to activate the phone. If you are just synching the PIM and not using e-mail redirection then it might work.
2. Yes

I'm not on BES. i'm using BIS on tmobile

it "should" work fine. my wife and i sync our phones on one DM. we use different folders in outlook.

1) Yes. I sync my 7105t as my main BB, and charge my backup 7100t and 7730 all on the same pc and it recognizes each PIN. BUT, my 7730 is no longer able to be upgraded but I still charge it and have been able to add some apps to it.

2) Yes. My 7100t and 7105t both have T-Mo's 4.1 OS, but my 7730 still has T-Mo's 4.0 OS (too old to be upgraded LOL)

okey thanks ericaJ
