Turn your Wi-Fi iPad into iPad 3G with iPhone 4

Note: The ‘iPhone Wi-Fi hotspot’ feature is for the iPhone 4 only

Apple iPad Wi-Fi + 3G is expensive than Wi-Fi iPad. But if you already have an iPhone 4, then you can save extra $130 and access 3G network with Wi-Fi iPad by using iPhone as a 3G mobile Wi-Fi hotspot. If iPhone is using 3G connection, then you can turn on “Wi-Fi Tethering” on iPhone and share Internet connection on other mobile devices like laptops, iPad, PSP or any other Wi-Fi enabled devices. If you want to turn on hotspot on iPhone, then here is the tutorial.


How to turn your iPhone into a 3G mobile hotspot

1.Upgrade your iPhone 4 to 4.3 IOS:
Just plug your iPhone 4 into PC and open iTunes, click the “check for an update” button. (If your iPhone 4 is already higher than 4.3 IOS, ignore this step)

2. How to set up your iPhone Wi-Fi hotspot

Go to the settings menu, in “settings”, you’ll see a new “personal hotspot” menu item. Tap it.

In the personal hotspot menu, slide the “personal hotspot” option to “on”.

You’ll note that Apple has allocated the connection a default password which is shown on this screen too. You can either use it (as each iPhone 4 gets a different random password) or change it to something you can more easily remember by tapping on it.

Then, on your iPad’s Wi-Fi menu, you should see your iPhone pop up in the list after a few seconds. The network name is the name of your iPhone in iTunes.

IPhone 4 + Personal Hotspot + Wi-Fi iPad: Possible, but with drawbacks

“Awesome! So this means if I have an iPhone 4, there’s no reason to get an iPad with built-in 3G, right?” Well, no, that’s not necessarily true. I can think of 3 things you lose if you go Wi-Fi-only with your iPad and use your iPhone 4 as a hotspot.

1.Locked phone makes locked tablet
In most countries the iPhone is locked to whatever carrier you buy it from; the iPad has no carrier locks whatsoever, and you can roam between carriers (or between countries) at a whim.

2. Additional fee

Many people think that use the iPhone Wi-Fi hotspot + Wi-Fi iPad saves money, the truth is that in several countries (most notably the US) you’ll pay an extra monthly fee to enable Personal Hotspot on your iPhone 4. In the States this comes to $20 per month, which gives you an extra 2 GB of monthly data, for a total of 4 GB per month on your iPhone’s plan.

3. Longevity

When using your iPhone 4 as a 3G mobile hotspot, you can expect the iPhone 4′s battery to last for only about five hours before it needs to be charged. But the iPad 3G supports 9 hours surfing over 3G.

Turn your Wi-Fi iPad into iPad 3G with a 3G Wi-Fi hotspot

Recently I read an article which is about “How to turn Wi-Fi iPad into an iPad 3G with a 3G hotspot?” It mentioned a tool named E583C WiFi Hotspot, and actually it’s a kind of 3G Router which can be used as a 3G mobile hotspot by just inserting a 3G SIM Card and not other settings needed. It can share the network with at least 5 Wi-Fi enabled devices without additional fee or longevity problem, and it is a unlocked 3G Router cost about 140 dollars.
