The phone has hung up because there are errors in the software. So to reset remove the battery and the memory card from the phone. Using your PC , scan the memory card for any corrupt files or media files with virus- it is possible when they are downloaded from unsafe sites. If so remove or format the card. Now replace the card and battery and switch on the phone. If the phone hangs up then it is confirmed that the software is corrupt and will need a reinstallation. Seeking help from the authorized service /support centre is most ideal. Take estimate and decide.

That means that the speaker in your phone is broken. This is very common in Sony Ericsson phones for some reason. You can buy speakers on-line or at some specialty stores for phones. However if you do buy one on-line the seller will expect you to know how to install it and it may be more of a risk to try to dissect your $200 rather than to just bring it into a radio shack or other kind of phone store

Call 3 Care and ask them to unlock it, they might do it for free. I've unlocked 2 phones with them free of charge like that. If they won't do it free, read here how to unlock your phone.
