Of iPhone 4, Signal Problems and Multitasking

I just made a discovery, or perhaps shall I say, saw a relationship between the iPhone 4 signal loss problems, the way the phone is held, and multitasking. You’ve probably read about how the iPhone 4 encounters some problems with its cellular signal strength when held in a certain way. Steve Jobs answer was to simply not hold it that way. It seems that the iPhone 4 works better if held in the right hand. Well, I started to think about how I held my hand phone. Hmm. I use my left hand.

So the iPhone users around me will say, since I’m right-handed, why am I not using my right hand? Interesting question. I suppose, holding a phone doesn’t take a lot of strength, nor dexterity. It seems like a secondary activity that can be delegated to the non-master hand, so that my master hand is free to do other things. Like taking notes while answering a call. Type on a keyboard. Open a door. Eat. Hmm, and operate a certain type of heavy mobile machinery while traveling on the road. These other activities are best done with my right hand.

If the iPhone 4 had to be held with the right hand, it seems somewhat inconvenient to carry out other tasks simultaneously.

Then, I saw the connection. The iPhone doesn’t multitask. Neither, probably, do their users. I can just imagine, if an iPhone user were on the phone (held the right way, of course) walking down toward a door, they would hang up the call, return the iPhone to the owner’s pocket (or wherever), then open the door (the right way too) and walk through it. After that, the call can be resumed. Too difficult? Well, basically you should just sit still when making a call. Try not to do any other thing at the same time.

Sounds really silly?

That’s why iOS 4 now has to support multitasking.
