My i760 phone is freezing up when using the quick dial keys (hold and press number 2 for wife, etc.). It also has been freezing on incoming calls. It rings once, then freezes. I have to do a soft reset to get it to work again.

Software installed:
spb Diary
spb Mobile Shell
Windows Live Search
Windows Live (just added this last week)

I had spb Backup on it, but took it off after this problem began happening. I am wondering if Windows Live might be the problem? Any other ideas on how to fix this issue?
