Phone Repair

My cell phone just went mad. When I press on the keypad, the screen will black out. I need to wait the light on the keypad to be off, then only I can press another key and see the screen again. I have no idea what went wrong, that is why I send the phone to the Sony Ericsson service centre for repair.

I went there this afternoon. After checking, they told me the display was broken, need to change a new one. There are 2 types: local and original. Local is RM130 and without warranty. Original costs RM170 and has 1 month warranty. I chose the latter. I can get it back by tomorrow. RM170 sounds expensive, but if after change it and it goes OK, it is still worth it.

I have been spending quite a lot recently. First, car's air conditioning broke down. The repair fee is not cheap. Now, phone's problem. What's next?
