Yes, I meant everyone I know of personally, along with the other reported instances overseas, had their white iPhone 3GS overheat and turn brown.

Well, since the 3GS isn't jailbreakable yet (at least be the general public) I doubt that this is the case.

I've noticed that when Bluetooth is on, it remains 'Discoverable' with no option to take it out of that mode. Coming from the world of Windows Mobile, I've been accustomed to putting the device in Discoverable mode when I need to hook it up with something new. My PC also works this way, even recommending in the settings screen to turn off discovery mode when everything is hooked up.

Even after I connected my iPhone with my headphones, it's still looking for other devices, as well as being discoverable.

I actually have a 1st gen iPod Touch and have had heat issues since I installed OS 3.0. Are there any other iPod Touch owners with this problem?

[MrLarrity]

Yea, I noticed my 3GS warming up when using GPS or playing games as well, but it is in a case. Even with the case I can feel some heat although I don't know how hot it ultimately gets.

I'd be lying if I said it didn't worry me, but even old cell phones would heat up when talking for about 30 mins. Thank God for the year warranty.

As long as it doesn't explode, I am fine. Wouldn't trade my iPhone for anything.

Yeah...haha that's true. Think about other phones and devices. ANYTHING you use a lot gets hot. Of course the oven does, but then think of the TV and all sorts of stereo equipment or other smart phones. Big Screen WiFi lots of processor work... yeah that's heat.

Oh and yes, the one year warranty is good.

I too have had this happen. I ran a series of real world tests to see whic items were making the iphone 3gs heat up so quickly. I found after trying all 15 various configurations & it definetly is the Bluetooth device causing the heat. An example you can try at home is to turn off your actual bluetooth device such as a headset while leaving the bluetooth on. After a few minutes it turns into a little toaster oven but still operates just fine. I did notice a bit of a battery drain more so but cannot determine if it accelarates the drain as the iphone 3gs heats up or it is just the bluetooth being on. Either way the battery still lasts a lot longer than my old 3g, so much in fact i know leave Push on all the time as well as the bluetooth abled. The battery gets me through a 10 hour work day as a bartender & have found to make sure its charged fully before work for i let my bar guests play with it to waste some time. So many free games- who can refuse.

Aren't they great for work? When a guest asks for directions, you can pull it up with Google Maps, show them, Street-View the destination and offer to email it to them if they have a smartphone. What I've also been running into is they often have an iPhone -- but never knew they could do that.

I went to perform the 'test' you mentioned of leaving Bluetooth on with no device in range, and realized I'd left Bluetooth on overnight, I only it have it paired with one headset, and that was off. It was cool to the touch when I picked it up. I've had the black 32g 3GS since launch, used it a lot with all the radios, camera, and GSP and it hasn't gotten hot once.

This isn't an issue that effects all iPhone 3GS's...

While there is not an official "Activity Monitor" for the iPhone, I have installed iStat, which get's me a bit closer to monitoring at least memory-usage on the phone. It also allows me to free up memory that closed apps have not returned to the system. Memory allocation is less of an issue now with my GS, but was an issue with my 3G, which would occasionally crash apps if I was running low on memory.
As far as overheating, the phone is never uncomfortably warm during heavy usage.

I love iStat! It's cool to use. I'm hoping a future update will enable access to the temperature sensor so we can all clamor over that data. :)

A poster above claims that the iphone cases are also a cause of this overheating, I do not really find it hard to believe this seeing as indeed it cuts off direct circulation of air, then again, an iphone in a pocket is also not really like being in a windtunnel. Is it really not that advisable to put a case on your iphone?

[MrLarrity]

diasmo, of course you should buy a case for your iPhone. These little computers are very sensitive. It only takes one drop, or one drop of water and then you will need about $600 to replace the thing. There is no insurance policy for the iPhone through Apple or ATT.

Best Buy's policy charges you like $15 a month to insure the iPhone, so it is a rip off. My iSkin case cost me $40 which was also a rip off, but it has port covers to keep the water out, plus it is silicone, so the padding will protect a modest drop. Just replacing the screen alone will cost you $200 from the Apple Store, call to verify if you need to.

My point is that the heat trapped in a case is nothing compared to the protection they provide. I am sad to hear of anyone who drops, or loses thier iPhone, because I know that could be me next time. I want you to enjoy your device well over the next year or two while you are paying for it, so protect it with a good case and don't worry about it getting hot. Just be sure to monitor extended use and using it in hot temps and bad weather.

Ok thanks for that :) though it is not as cheap here as in the US unfortunately :(

cost of iphone: 575 euro (we have no bundle sales here combining subscription and purchase of phone)

monthly subscription cost: 45 euro (ok, granted, there is a cheaper rate but the amount of data is just pathetic, the 45 euro one is only 500 mb / Month!)

i did not take insurance on the iphone but will get applecare in a year :)



oh, and i'll be getting a case aswell!

Bought my first iPhone several weeks ago. Bought the 3G for $99. Didn't notice any excessive battery use or heat. Downloaded the software update. Began to notice the battery didn't last for more than a day and a half. Not an excessive user. Also, after the download, the phone became noticeably warmer after making a phone call. Don't have but a couple apps loaded.

Went to charge the phone last night using the hardware that came with the phone. The phone got hot and the USB connection to the wall was hot also. Decided to restore phone to the original software. So far, none of the above conditions have occurred.
