I reset all the apps on my phone because I had a problem. then when I tried to add the ones that I need like Facebook, CrunchSMS, etc, from the Baclberry Desktop Manager, it gets added to the Add-On application list. how do you move it to the third party list?
That's a new one on me, but I've never used an 8520 and never been a T-Mobile user. I've forwarded your question to some other folks to see if anyone has any suggestions.
Addons should only be Rim sponsored apps, such as Maps, Traffic and Yahoo Messenger. How were the apps backed up on your PC, and which version of DM are you using?
