You may have read my post on tethering with Android.

However, I did switch over to iPhone!

Now, you can tether using the iPhone by paying AT&T or Verizon, and you’ll get a portable hotspot.

But that’s extremely expensive!

Here’s an easier way: MiWi.

MiWi is an application available from Cydia (you need to be jailbroken, if you have a Verizon iPhone 4 click here) for $20. That may sound expensive, but it’s much cheaper than spending $20 each month! If you have read elsewhere about the Sinful repo, you can get it for free, but that’s cheating the developer out of what he has earned, so I don’t encourage it.

Installation

If you know how to get apps from Cydia, skip this paragraph. If you don’t, continue reading. To get MiWi, open the Cydia app from your homescreen, wait for all of the data to “reload,” and click search. Type in MiWi, and tap the result. Then, click “Install” in the top right corner, followed by “Confirm.” Let it install, and then click the big black button at the bottom. MiWi will now be on your homescreen.

Use

MiWi is an extremely simple app.

Upon opening it, you will be greeted with three tethering possibilities: USB, Bluetooth, and WiFi.

Bluetooth is advertised to use mainly with iDevices, however I don’t like bluetooth tethering as it is unreliable compared to USB and WiFi tethering.

USB Tethering only works with Laptops, and I had a terrible experience with it. Although it may boast a faster connection, you need to get it connected in the first place. That’s where I had my problems.

So that leaves WiFi. And let me just say, getting WiFi to work is painlessly easy.

You can easily setup a WiFi Password, change your SSID (network name), and even control which computers are on the network. Even better, you will get a notification bar at the top of your screen that tells you how much has been downloaded and uploaded. Handy!

The speed isn’t too shabby either! I was able to crank 1.0MB/s down, which isn’t too bad. It works great for email and basic web browsing, but I wouldn’t try to stream video over it.

Conclusion

MiWi works great for WiFi tethering. But I wouldn’t recommend it for USB or Bluetooth, as they are far less reliable.
