Bugs after updating iphone October 2011.

I have just updated the software in iPhone 4 in October 2011 and I have several bugs.

For me the most important is that now my live messenger program doesn't work properly anymore.

- First I can't see who is writing me anymore when I am in another program. It just come with a message PN_MSG_IM.

- Secondly when I return to messenger to read the incoming message, the messenger program collaps and close down. When I reopen messenger, the messages doesn't appear. I didn't have this issue with the previous software version on iPhone.

- Thirdly I cannot share photos via Live messenger anymore. When I try to share a photo via the chat in messenger the program collaps.

These are the bugs I have met so far.

I have tried to erase and reinstall Live messenger but it doesn't help. Rebooting the phone didn't help either.

I also have the same problem with a back gammon game that collaps in the middle of the game. Never happened before the update in October 2011.

Anyone has the same issue? What to do about it?
