Fix for iMessage not working after latest update

After we updated our iPhone 4 we could no longer send pictures through iMessage. After days of being on the phone to Verizon, apple, and Internet provider Comcast, and nobody taking responsibility, finally got a Comcast guy here and he changed my router to default settings. Changed password back to original on back of router. Fixed the problem. I knew it was a problem with my Wi-Fi because I went to Starbucks and connected to their wi if and iMessage sent pictures.

How much would it cost to buy the iPhone 4S before my contract is up?

I have the iPhone 3GS right now but it's messed up. The home button sticks the ring\silent switch is glitchy and I just recently cracked my whole screen.
