It took days for me to find this out, I had a problem with my BBZ10 last week. It just stopped working. I couldn't do anything after as it didn't recognize its usb and couldn't be charge either. And to think, my phone wasn't dropped or even got wet, it just died suddenly. I have read forums about the same problem and seems there wasn't a solution to it as everything just collapsed. With the usb and battery on the fritz, sure nothing can be done. I suspect though that the updates might have something to do with it.
I went to Terminal 21 as I remember there was a BB shop in there near the movie theathers but to my surpise, it was gone. I was glad a very nice man who has a stall next to the area informed me where to get my unit checked. Of course, as long as the phone is still under warranty and was purchased in Thailand. I've also learnt that there's no need for any document warranty as the service center will just scan the unit and find out when the unit was bought. So basically, just go to the authourized service center and bring the unit.
|BlackBerry Authorized Service Center under warranty.|
The BB authorised center is called SIS, it is located at the fourth floor of Fortune Tower, fronting Central Rama 9. It is accessible by MRT and get off at Rama 9 station. I went there yesterday and they got my unit. I was told I can get it back after a month as the unit will be sent to Malaysia for checking. That means a month of no phone; however, Fortune Tower is an IT hub, it's easy to get another unit in the area. I got a new one yesterday that I can use in the meantime. To those who have BB problems and is still under warranty, no need to worry, just go to SIS.
