Hi all,
new to this forum thing but some stuff hear helped me so... wat goes around comes around

.
Anywho i installed the v20 update and i had a few problems.
1. Asked me for my unlock code, i typed my one in but it would not accept it.
2. The search feature in home menu was giving me an error message when i tried to access it.
3. I didn't have the app.update thing or the dictionary applications.
To resolve (for me anyway!!!)
1. reinstall the update
2. hard reset your phone using *#7370*
What happened.
1. my unlock code reset to 12345
2. all updated stuff listed appeared and works
3. the search feature works.
I hope this helps and works for you guys.
