I dl'ed app stalker for my Torch but it doesnt work at all. I open it and it goes to the "stalking apps, please wait" screen, and never advances past there.
I downloaded this app last week on my bold 9650 and it worked great for maybe 4 days. For the last 3 or 4 days I haven't received a notification about price drops. I still can get by the "stalking apps" screen though.
