Guide to Unlocking iPhone 3g

Thanks to Simon from http://www.simonblog.com we now have a very easy and precise documentation of how someone could jailbreak and unlock a locked iPhone (2g/3g/3gs) using ultrasn0w, which is the software solution to unlock the iPhone from the "Dev Team" (http://blog.iphone-dev.org/). I have tried this myself and it works like a walk in the park. I had my iPhone 3g unlocked with the new OS3.0 in 10 minutes flat. Jailbreaking gives you Cydia (an alternative to the App Store) in your iPhone which you can use to install other applications being developed by iPhone developers. Some of the useful Cydia apps that I would recommend are

1. SBSettings (easy way to toggle settings like wifi,brightness, power off etc right from the home screen)
2. Battery % display (Displays the battery remaining as a %)
3. Cyrocorder (video recorder for iPhone 2g/3g)
4. Five column springboard (2 can see icons in 5 columns instead of the default 4)
5. Five Icon Dock (Add a fifth icon in the dock on the home screen)

Disclaimer : jailbreaking and unlocking voids your warranty and hence this should be tried at your own risk only.

How to sit infront of a computer

Aaaaah ! My back....ooooh my neck....damn my wrists hurt....why are my eyes so itchy.

I am sure all of us at some point have spoken the above words. Fact is learning to sit and work ergonomically is a "soft skill" necessary for modern day work life. I too have faced various aches and pains due to horrible ergonomic positions in my work life and after working 10 yrs in my industry I have finally been able to get an ergonomic position I am comfortable in. Here are some tips.

1. Unclutter your workspace. Your workspace should help you do your work better, and not hamper it. Things like the phone, monitor and documents should be at arms length distance from where you it.

2. "The chair". Getting the right chair is very important. A good chair should have height adjustment, a height adjustable arm rest and a good adjustable backrest at least.Having a 5 wheel chair is also helpful to move around your workspace.

3.Your back (the most important part). Your back should be straight and at 90-110 degrees with the seat of the chair. Try not to slouch or lay back on the chair.

4. Your feet should be flat on the floor and the back of your knees should make a 90 degree angle. The same is true for your elbows, with your arms resting on the armrest of your chair.

5. Your key board should be at a height just below (or at the same height) your armrest so that your arms do not stress while typing on the keyboard. Make sure your wrists are not turned upwards or too downwards and lie straight on the keyboard. Your mouse should ideally be close to your keyboard (preferably on the keyboard tray itself).

6.Finally the monitor should be at arms length distance away from your eyes. The top of the monitor should be at eye level. Make sure the monitor is nice and clear (resolution and brightness wise). If you are near a windows, blinds would help in better viewing. Also adjusting the screen resolution based on your liking should help.

Last but not the least frequent breaks are recommended (5 mins every hour) to rest your body. Get up from your desk every hour and take a small walk. Have a bottle of water ready with you at your desk and aim to finish at least 2 litres of water during your 8-10 hour work schedule (remember the human body actually needs 3 litres of water a day).

Here are some links (I referred) that should also help you get the right posture for your computer use.
