LG KG245 weird fault

Question

hello, my lg kg245 phone cut out in the middle of a call last week. when i powered it back on it is now behaving very oddly.... it hangs for ages at switch on, then finally comes to its normal screen after about 3 minutes rather than 8 seconds. when i try to access menu items it says 'please wait' but then after a while goes back to the main screen without getting into the menu's. most of my phone contacts are in the fone not the sim coz when i tried to transfer them the 245 said i didnt have enough room on sim. if i cant get the fone to work is there a way of getting my numbers and texts out of the phone memory? thanks for any advice.....
