iPhone 4 Random Crash Black Screen of Death

Hi anyone,

I bought an iPhone 4 a few months back from the UK. After bringing it to my home country (Bangladesh), I used it a few days with no problems. But after a few days, it started crashing. Then the frequency of crash got high. And the crashes are very very random. Following are a few ways it crashes.

1. The screen gets distorted and starts fading and goes black.

2. The screen goes black all on a sudden

3. The phone goes to sleep and goes dead

4. While booting (the silver apple icon) it dies.

I am so frustrated with it. It never reboots with the crash (screen blacking out). It happens so often now that the phone is almost unusable. The restart is even more annoying.

1. Sometimes it starts booting just by holding the sleep/standby button for a few seconds.

2. Sometimes it starts booting if I hold the sleep/standby button for long (10/15 secs)

3. Sometimes I need to hold the Sleep/Standby + Home button for long time

4. Sometimes it won't start what ever I do, once I tried the whole day even then it wouldn't start.

I tried to reset the phone from iTunes and downgrade the iOS, I never could. Always 1600 or 2001 error. I could always upgrade. I reset it from within the phone once  Config > General > Reset > Reset All even that didnt work. I have accumulated all the crash reports. Is there anyway to pass it to the experts for analysis? I don't know what else to do, it's nearly impossible to go to uk now. Any help please? And also, I just have the box with me, I misplaced all the rest of the papers. If I do manage to get it to uk, can I replace it?
