I personally like to re-setup my phone, but then again, I don't have a lot of apps. The one's I do have are either from market place or open market and can just be reloaded from your profile on those apps. The others I have are .cab files that I just have saved on my SD card, so I go back and reinstall. As for contacts/calendar, I use windows mobile device and back up through outlook....occasionally I'll back up using windows myphone.

That being said, when you do upgrade to 6.5, it will wipe your phone so you'll have to decide which is the best way for you to back everything up.

Hope this helps.
