issue resolved. for anyone else who manually updated to 8107:
"If you updated your phone using the "main" 8107 cab file, but did not install the language file this will cause the problem you described.
"main" 8107 cab is about 5.11M in size
8107 cab language (english version) is about 80k in size
If you only update your phone with the main 8107 cab file and do not include the language cab, your phone tile and other items associated with the phone function will not work properly.
This is a two step process.
I too had the problem, but I had thought I had updated using both cab files. Once I just updated with the language cab file again, the phone worked prefectly."
