(Updated 1\/26\/2015)\r\nIf you have the best iPhone you will like this. Knowing that they were missing out on yet another way to nickel and dime their customers, AT&T worked with Apple and added a hotspot feature in iOS 4.3 and above, the result is that iPhone 4 and above users can turn their iPhone into a wireless hotspot with yet another hefty monthly fee.\u00a0 Verizon users can also get the privilege for a similar additional fee. \u00a0But for the easy nature of simply flipping a switch, or for those not comfortable with jailbreaking their phone, it\u2019s a convenient, but costly method. \u00a0 And if you like to play by the rules, well, enabling your iPhone's hotspot feature couldn't be easier.\u00a0 One warning though, if you're currently grandfathered into AT&Ts unlimited data plan, once you enable the hotspot feature, you will have forfeited your all your can eat days in favor of their more limited tiered plans.\r\n\r\nSet it up on your iPhone (legal option)\r\nUpdate: With iOS 7 now out, the setup process is slightly different to create a WiFi HotSpot. \u00a0To do so:\r\n\r\n1. Tap "Settings" from the Home Screen\u00a0Then tap "Cellular"\r\n\r\n\r\n\r\n2. 4 rows down there should be "Set Up Personal Hotspot" in Blue. \u00a0Tap that.\r\n\r\n\r\n\r\n3. Click "Go to Website" (AT&T in my case)\r\n\r\n\r\n\r\n4. Once at the Carrier's website you'll need to add the appropriate plan. \u00a0For AT&T users you'll have to select a finite data plan. \u00a0Which is to say\u00a0Unlimited Data users, those that are grandfathered in, are precluded from setting up a WiFi Hotspot.\r\n\r\n5. Finally, once you have a plan, you'll need to set up your iPhone to allow other devices to connect to it. \u00a0Charges will apply, but all it takes is two simple steps: open Settings, then Personal Hotspot. That will instantly give you an on\/off switch for the hotspot if you've already set it up. If not, the iPhone will show you exactly how to do it in clear, easy steps.\r\n\r\n\r\n\r\n6. Just in case you haven't set it up already, see Apple's above instructions. They are identical across AT&T, Verizon, and Sprint. The hotspot can share data in three ways: over the air (like any Wi-Fi router), over Bluetooth, and via USB. I recommend only Wi-Fi and USB; Bluetooth is slower and will drain your battery faster, while Wi-Fi can be shared with up to five people and USB charges the phone while plugged in.\r\nJailbreak Your iPhone (illegal option)\r\n\r\nNow I know what you\u2019re thinking ... it\u2019ll void my warranty! \u00a0It\u2019s illegal! \u00a0It\u2019ll mess up my phone and I won\u2019t get it back to the way it was! \u00a0That's not entirely true. Jailbreaking your iPhone can void your warranty, but thousands of people jailbreak their iPhones and have no problem or any need for the warranty. Furthermore, once you remove the jailbreak the warranty comes back in place. After all, Apple doesn't know that you jailbroke it. If you don\u2019t like it, you can easily go into iTunes and restore it to the way it was.\r\n\r\nAnd it\u2019s not illegal either. \u00a0According to the US Library of Congress Copyright office, it is perfectly legal to jailbreak your phone. \u00a0The only reason to not jailbreak your phone is that when there are updates, you have to reset your phone back to the way it was to update it. \u00a0Then you have to wait for the jailbreak tools figure that out before you can free it up again. \u00a0But these days, it\u2019s largely a \u00a0painless process now.\r\n\r\nThere are a lot of different ways to jailbreak your iPhone, but depending on the model and operating system you may not be able to. Currently there is no public jailbreak for the iPhone 5 or iPhone 4S in iOS 6. The same applies to the 5th generation iPod Touch and iPad. So if you have a 4S and want to tether, don't update to iOS 6.\r\n\r\nFor instructions on how to Jailbreak your iPhone (and whether it's even possible), check out Redmond Pie. They have an excellent section for jailbreakers. Once you've jailbroken your phone, it'll install an application called Cydia, which is an app store for jailbroken apps. There are others, but Cydia is the largest and best.\r\n\r\n1. \u00a0Open Cydia and download MyWi\r\n\r\nMyWi is the hotspot utility that will enable you to unofficially turn your phone into a hotspot. \u00a0You can try it out for free, but if you plan to use it beyond the free trial, MyWi costs $20. You can set passwords, change your SSID settings, make security settings, etc.\u00a0 Once you have MyWi installed and enabled, you will notice a blue bar at the top of your screen showing the hotspot connection active and functioning.\u00a0 It even shows how much data you are using downloading and transmitting - a handy feature.\r\n\r\n2. Surf to your heart's content ... or until you're caught\r\n\r\nOnce you're all set up, you can acquire your phone's WiFi hotspot signal and you're off to the races.\u00a0 It's a simple matter of choosing your iPhone from the list of wireless routers your gadget or laptop sees and inputting the password.\r\n\r\nA few things though.\u00a0 First, using your iPhone as a wireless hotspot will drain your phone's battery as fast as continually using your GPS feature.\u00a0 But you can get a few hours of hotspot use easy from it.\u00a0 Or, you can attach your phone to your laptop via USB and not only have the security of a wired connection, but also not drain your phone battery thanks to the USB charge feature.\r\n\r\nAdditionally, wireless carriers do not allow for their customers to use their data however you'd like. \u00a0If they see an influx of downloads or uploads or track webpage data that isn't consistent with smartphones (the size of downloaded pages don't match your phone's screen size, for example), even if you have an unlimited data plan (grandfathered on AT&T or through Sprint), they will send you a text message stating that if you'd like to tether it's an additional fee. \u00a0If you don't heed the subtle warning, they'll start charging you and will offer access to the built-in hotspot feature.\r\n\r\nThe reality is that if you plan on using the hotspot today on an iPhone, it's just a matter of time before you have to pay. If you use it minimally, you may never get caught by your provider. I've had MyWi for years, but only use it in case of emergency. A few have come up, but they've never resulted in AT&T (my carrier) forcing me to upgrade my data plan.\r\n\r\nIn the end, it may just be easier to get a MiFi card which will provide 4G wireless hot-spotting for a minimal fee. \u00a0They range from $20-60 a month depending on data usage and doesn\u2019t require jailbreaking or catching the ire of your wireless carrier.
