I was wondering, I am currently overseas and am using a relative's desktop. I am thinking of loading desktop manager and downloading some games from handago and loading them onto my phone... are there any possible problems my blackberry 8830 may encounter by using another desktop other than the one at home, and will the games I download be able to be offloaded to my desktop at home once I sync it when I return home?

Nope no problems at all.

Just be careful if you're on BES. Do not install with the BES option or else you'll break your BES connection when you connect to your relative's desktop.

IIRC App Loader doesn't pull anything from the BB. It can load or remove apps but that's it.
