Help Restoring to factory settings

[Amby]

Hi,

I've installed Whatsapp on my Desire HD but the push notifications aren't working very well. Hence, I'm thinking of restoring my phone to factory settings to see if that would help. However, I'm unsure as to whether my other applications' progress will be affected, such as my Angry Birds progress!
Any help would be greatly appreciated! Thanks!

Just delete the app and see what happens If you do a factory reset your Angry Birds data will be gone
