Take Control of iPhone and iPod touch Networking & Security, iOS 4 Edition

Connect with confidence with Wi-Fi, 3G, and Bluetooth!

Basic network connections from an iPhone or iPod touch are simple to make, but sometimes you need to go beyond the basics, whether to make unusual connections or to establish connections that are private and secure. In this ebook, you’ll learn how networking expert Glenn Fleishman thinks about networking, and profit from his explanations and advice on key networking topics, such as the ins and outs of how you can create secure Wi-Fi connections, exploit alternative 3G data plans, set up your iPhone as a personal hotspot, conserve 3G data, connect Bluetooth devices, access files stored on local computers and in the cloud, protect personal data on your mobile device, and use Find My iPhone and other remote tracking software.

Which devices are discussed? If you are using an iPhone 3G or 2nd-generation iPod touch, this ebook is for you. Those devices cannot be upgraded past iOS 4. Note that the data plans and third-party apps described in this ebook may have changed over time.

More Info

Inside, you’ll find advice and steps for how to:

  • Make Wi-Fi connections: Connect via Wi-Fi at home or work, at a public hotspot, and with (or without) various forms of security. Glenn discusses the more modern and favored WPA and WPA2 security methods, and he explains why WEP and MAC addressing should be avoided (but how to deal with them if you must). You’ll also find tips for setting up your home network to best work with the 2.4 GHz 802.11n networking found in the iPhone 4 and fourth-generation iPod touch.
  • Connect your iPhone via 3G: Decide which data plan to sign up for, and get advice on limiting your use of the 3G network to stay within the bounds of your plan. Although Glenn focuses on plans available in the United States, overall, the information he provides is appropriate for everyone, no matter where you are. You’ll also find tips about traveling to a different country with your iPhone.
  • Connect your iPod touch via 3G: Learn about alternative 3G plans (in the United States) that put various mobile devices on the Internet.
  • Use Bluetooth: Connect Bluetooth devices, such as headsets and keyboards, to your iPhone or iPod touch. Also learn how peer-to-peer pairing lets you connect multiple iOS devices to play a game.
  • Access remote documents: Learn how to access remote documents wirelessly and find steps for using a variety of file-sharing apps, including Air Sharing HD, GoodReader, Dropbox, and iDisk.
  • Control a computer remotely: Use a third-party app on your iOS device to take control of other computers remotely. Specific steps are given for iTeleport and LogMeIn Ignition.
  • Protect your data and privacy: Understand what aspects of your documents, passwords, and privacy could be at risk should the wrong person gain access to your device or its network communications. You’ll get advice for how to take preventative actions, and learn what you can do if your device is lost or stolen.
What's New

What’s New in Version 1.2

The purpose of this update was to overhaul the tethering chapter to reflect the new Personal Hotspot feature that appeared in iOS 4.2.6 for the Verizon Wireless iPhone 4 and in iOS 4.3 for the worldwide GSM iPhone 3GS and iPhone 4. The chapter includes all the information you need to use the updated feature. See Personal Hotspot and Tethering.

Also, minor details were changed or added to include information about the Verizon Wireless iPhone 4, and some information about mobile broadband alternatives was removed because it was outdated, no longer relevant, or changing too fast to be useful.

What Was New in Version 1.1

Here are the highlights of changes made to create version 1.1:

  • The chapter about tethering has more accurate and complete information about tethering plans (in version 1.2 that chapter was entirely overhauled and is now called Personal Hotspot and Tethering).
  • Enable Remote Access (for iTeleport) has updated steps.
  • Find My iOS Device via MobileMe has a brief note and a few edits about a new, free way to use Apple’s device-finding service.
  • Remote Tracking Software is updated in various ways, including a look at the new version of GadgetTrak.
Update Plans

March 4, 2015 – We won’t be updating this book again due to the effort of matching pace with new versions of iOS.

  1. Running a Mail Spam Filter on an iPad or iPhone

    Take Control reader Genevieve S. wrote in with an interesting question a few days ago:

    Genevieve: Do you know any third-party app that can filter mail on iPad and iPhone—i.e., apply rules?
    Tonya’s reply: I don’t know of any apps that can filter mail locally on the iPad, but I’ve cc’d Adam and Joe here to see if either of them has a suggestion. Personally, I use my gmail account on the iPad, and Google handles the filtering on the server.
    Joe’s reply: There is an app called ibisMail, which comes in both iPad and iPhone versions, that does filtering on the device. However, I do what Tonya does—let a server-based filter do all the work before messages appear on any of my devices.
    Genevieve: Thank you for responding. I use the Gmail filter too, but the AT&T/Yahoo filter is lousy. This is not a problem when receiving mail on the Mac—the rules in Mail handle the leakage—but if I read the mail on the iPhone, a local filter would help.
    Adam jumps in: You could forward the other account to Gmail to get the benefit of its filter. Lots of people do that. smile
    Genevieve: Great idea!!

    In the third edition of Take Control of Mail on the iPad, iPhone, and iPod touch, Joe touches on email forwarding in “Decide Which Account(s) to Use,” and he references a Macworld article that he wrote—Streamline e-mail with Gmail. The Macworld article discusses how to forward a non-Gmail email account through Gmail.

  2. Changes to LogMeIn App

    As 2011 wound down to its final weeks, LogMeIn changed both the features and pricing of the LogMeIn Ignition app covered in this book. There is now a free version, named simply LogMeIn, and a for-pay version, LogMeIn Pro. Glenn Fleishman describes the changes in his article, “LogMeIn App for iOS Set Free and Gains Pro Upgrade,” 23 December 2011.

  3. AT&T Changes iPhone Data Plans

    As of 22 January 2012, AT&T has raised both the cost and the usage allotment of two of its smartphone data plans. The lowest tier now costs $20 a month for 300 MB of data usage; the previous plan cost $15 for 200 MB. Those who exceed the 300 MB are now charged $20 for an additional 300 MB. The next higher tier now costs $30 a month instead of $25, but now offers 3 GB of usage instead of 2 GB; this plan retains the $10 for each additional 1 GB of usage. Those who currently have the older plans can keep them, but if they change to any of the new plans they cannot then return to the older plans. Glenn Fleishman slices and dices the new plans in his TidBITS article, “AT&T Raises Data Plan Prices for New Customers,” 18 January 2012.

  4. Apple Now Selling Unlocked iPhones

    Apple today quietly began selling unlocked iPhones via the online Apple Store. Mark Anbinder’s TidBITS article, “Apple Quietly Adds Unlocked iPhones to Online Apple Store,” 14 June 2011, explains what it all means.

  5. iOS 4.3.3 and iOS 4.2.8 Address Location Tracking Bugs

    On April 20, 2011, researchers Alasdair Allan and Pete Warden announced that they had discovered a file within iOS, consolidated.db, that seemingly tracked every single location that an iOS device has ever visited. Furthermore, this file was not encrypted and was backed up each time the iOS device synced with iTunes to a user’s computer, making the file available on the syncing computer as well as on the device. Although the file was actually known about for quite some time, a media firestorm erupted following the announcement, with many articles speculating that Apple was tracking users’ every move for unknown, but probably nefarious reasons, and which led to several requests by Congressional representatives for Apple to explain the purpose behind collecting the information.

    Apple responded within a week with a press release explaining what the consolidated.db file was, and why it was storing as much information as it seemed to be storing (see this TidBITS article, “Apple Addresses Location Controversy Questions,” 27 April 2011, for details on that press release). In a nutshell, Apple claimed that a bug was the reason that the file contained so much information, that the file was designed merely to help the iOS device’s Location Services feature establish location more easily, that it actually contained information about nearby Wi-Fi access points and cell towers rather than the device’s actual location, that no user-identifiable information was being sent back to Apple, and that a forthcoming release of iOS would address the bug and keep the file from being backed up to users’ computers.

    On May 4, Apple released two updates to iOS that address the problem. One, iOS 4.3.3, updates all GSM iPhone 3GS and iPhone 4 models, iPad and iPad 2 devices, and third and fourth generation iPod touch devices. The other, iOS 4.2.8, updates all CDMA iPhone 4s (see the TidBITS article, “iOS 4.3.3 and 4.2.8,” 4 May 2011). Updated devices now will store only a week’s worth of location information, and that information will not be backed up when the device syncs with iTunes. Furthermore, the location information cached by devices is erased whenever users disable Location Services.
