How to avoid overheating problem of iPhone 3GS

Couple of days ago I wrote a blog post about the overheating problem of iPhone 3GS due to its batteries, until then I didn’t experienced it personally but thanks to the London weather in last couple of days (32 degree Celsius), I noticed it well. Then dugged through Apple’s website and this is what I got.

iPhone is supposed to work under these conditions:

  • In the temperatures between 32 Fahrenheit to 95 Fahrenheit
  • Should be stored in between -4 degrees Fahrenheit and 113 degrees Fahrenheit (temperature in your car when you leave your iPhone in the dashboard, can be exceedingly more than 113F)

Symptoms of overheating

  • Temperature warning screen could appear
  • iPhone can loose or weakens the carrier signal
  • Screen can go less bright
  • Your iPhone screen can freeze

How to avoid overheating

  • Don’t leave your phone in your car on a hot day
  • Don’t listen to songs, use GPS or other use battery intensive apps for extended periods of time on a hot day
  • Avoid using your iPhone in direct sun light

These are mostly a common problem with any electronic device. Remember when you are watching a movie or playing a game on your Laptop, it heats up and its fan run faster than usual and when you are using a MS Word, it just keep on running smoothly, same is the case with iPhone, the more you use it on a hot day, it processor will emit more heat and that will degrades the performance of your phone.

Unlock application for iPhone 3GS has been released

A 20 year old hacker has found the mechanism to unlock new iPhone 3GS. George Hotz who was the first to unlock iPhone 3G claimed on his block that an app to unlock new phone is ready to use.  The application name is “purplera1n” and you have to have latest iTunes to install it.

Hacker says on his blog that jailbrake for Mac based computers is also on the way. Hotz claimed that he do not generally make the software for public use and users should back-up their data before trying to unlock. iPhone Dev team is yet to find unlock code.

I have figured out following 3 points:

  • Even the unlock application “purplera1n” is not free
  • It is still in beta version so can cause instability to your phone
  • It do not free you from current carrier

The last point is very important if you see it in broader sense, most of the people unlock their mobiles so they can use them when abroad with other carriers. What is the point to get your iPhone unlocked when I will not be able to choose any other carrier plus I will loose all the services given to my by my carrier here in UK, the O2. The best service I like is free Youtube. The unlocking will only return my iPhone to default factory settings leaving me out of all benefits given by my carrier.
