Problems with 2.3 on X2

[djtomczak678]

Just got a new X2 a few weeks ago, it's my first smart phone and I love it. Recently updated to 2.3 and now I'm having issues. I barely ever get notifications when I receive a new text. Nothing shows up at all, I must go to messaging and look at the conversations to see if i have a new text. Also while typing texts it often freezes and closes the keyboard. Ive had it reboot on me a few times while typing a text. Only possible explanation i can think of is I have the max messages set to 999, but isn't that just memory space?

Also on a side note i have some questions;
1. how do I set it for the phone to vibrate only in silent mode when I get a text, I don't want it to vibrate while sound is on.
2. Facebook pop noise doesn't work?
3. Facebook notifications don't make noise.

Thank you!
