Looks like I'm the first one with a device failure. Came back from work on Thursday to find the device off. After some trouble shooting I discovered that the charger output voltage fluctuated between 12V and 25V at about 2 second cycles. I'm sure it damaged the device. I took it back to the Sunninghill Postnet this morning, and they swopped it without any questions.

One question though.... I had my incoming ports opened on Wednesday but after the device swop it looks like it's close again...? Could port settings on their side be linked to the device ? Will they have to open it again ?

My suggestion: Request for port forwarding to be open once again.
Port forwarding could maybe be done with your UT-ID/Device serial number on their network as your device is mapped on their network..

Could be talking nonsense.
 
Just had a call from a Neotel rep to follow up on the device swop, he confirmed that the ports would have to be opened again.
 
Coincidence, or is there something with the power point you're using, try using a different plug :confused:
 
After the first one died I put the second one on my entertainment system's UPS. The power supply is fine.
 
Are you sure that you aren't overloading the RF power amplifier? If you are very far from the base station the device may need to increase the transmit power so much that the amplifier becomes very hot. Over time this will result in failure. These devices aren't designed to work on maximum transmit power for extended periods of time. You first need to check that the device is not overheating before trying out a new one otherwise it is quite likely that it will also fail after several weeks and this might be very costly. Also check that there aren't any short circuits on the driven element of your antenna. The antenna polarisation can also influence the signal strength and consequently the transmit power.

Thanks for the advice, but it turns out the device is ok after all. I took out the battery and after replacing it the phone started up ok.
 
Good to hear that the phone is still working!

If your phone has any air vents underneath it might still be worthwhile to consider placing it on top of a cheap (R50?) laptop cooler to improve the air flow - particularly if you are planning on downloading heavily during the summer. I regularly see postings about HSDPA modems overheating or failing ...

Some examples

The firmware is supposed to manage these kinds of scenarios. The iBurst UTD doesn't suffer from any ill effects when being very far from the BS.
 
I had an issue with my device. I put my shirt over the actual device and after 1 hour the device actually went dead with a black screen, had to remove the batteries from the device.
