Even so, I expect the market to be flooded with secondhand iPhones over the next few days and contract-free devices will sell for more money than those still locked to O2. In time, the hackers will unlock v2.0 iPhones but, for now, v1.1.4 is the one to get.<\/p>\n<p>I&#8217;ve been happily using my iPhone on an O2 contract since last November but, tomorrow, <a href=\"http:\/\/cgi.ebay.co.uk\/ws\/eBayISAPI.dll?ViewItem&amp;item=250266675788\">my iPhone auction on eBay will end<\/a> and I wanted to get it ready for sale.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/images\/iphone-on-vodafone.jpg?w=700&#038;ssl=1\" alt=\"iPhone working with a Vodafone UK SIM\" class=\"alignleft\">Last week, <a href=\"http:\/\/www.iclarified.com\/entry\/index.php?enid=847\">I unlocked (and &#8220;jailbroke&#8221;) the iPhone<\/a> using <a href=\"http:\/\/theiphoneproject.org\/index.php\/downloads?func=fileinfo&amp;id=3\">iLiberty+ v1.5.1 for Mac<\/a> and tested it with a Vodafone SIM (before listing it for sale) but tonight I followed the <a href=\"http:\/\/www.iclarified.com\/entry\/index.php?enid=1347\">instructions to securely wipe the iPhone<\/a> before I finally send it to the new owner.<\/p>\n<p>When I first jailbroke my iPhone, I found that I&#8217;d entered a whole new world of mobile application possibilities. When I first thought about getting an iPhone and using it with my previous (Vodafone) contract, I was concerned about the impact of unlocking and jailbreaking the device but I am amazed to see just how many applications the <a href=\"http:\/\/www.apptapp.com\/\">AppTapp<\/a> installer provides access to (especially with the Community Sources package installed). I really hope this ecosystem of iPhone underground application development is not killed off as the official <a href=\"http:\/\/www.apple.com\/iphone\/appstore\/\">Apple App Store<\/a> route to market takes over but I guess, as long as the device is tied to a particular operator in each market, there will always be people who want to use their iPhone on another network (and I found that jailbreaking takes no more effort than unlocking the device).<\/p>\n<p>So, with my iPhone restored to it&#8217;s factory defaults, then jailbroken, installer added to the splashscreen, the handset activated and unlocked, I set to work installing the <a href=\"http:\/\/www.iclarified.com\/entry\/index.php?enid=687\">BSD Subsystem 2.1<\/a> and <a href=\"http:\/\/www.iclarified.com\/entry\/index.php?enid=1349\">OpenSSH<\/a>. At first, I was downloading applications over O2&#8217;s 2G network, which took a long time (the BSD subsystem is 5.1MB), but then I figured I could share my MacBook&#8217;s Internet connection over Wi-Fi and that speeded things up considerably.<\/p>\n<p>Even though I could ping the phone (the IP address is displayed in the Wi-Fi settings), I was having trouble connecting to the phone, with my terminal session reporting:<\/p>\n<p><em>ssh: connect to host 10.0.2.3 port 22: Connection refused<\/em><\/p>\n<p>Googling turned up various posts suggesting using the <a href=\"http:\/\/www.installerapps.com\/2008\/02\/04\/bossprefs\/\">BossPrefs<\/a> application to ensure that OpenSSH is running but I couldn&#8217;t get BossPrefs to complete its own installation.<\/p>\n<p>Eventually, I figured that I could use iLiberty+ to install OpenSSH, after which I was able to copy a previously-downloaded copy of the <code>umount<\/code> utility to the iPhone:<\/p>\n<p><code>scp ~\/Desktop\/umount root@<em>ipaddress<\/em>:\/sbin\/umount<\/code><\/p>\n<p>After entering this command, something similar to the following should be displayed:<\/p>\n<p><em>The authenticity of host &#8216;<\/em>ipaddress<em> (<\/em>ipaddress<em>)&#8217; can&#8217;t be established.<\/em><br \/>\n<em>RSA key fingerprint is 8d:0c:46:44:6c:ff:25:7c:c3:d6:49:1b:6a:c5:31:8b.<\/em><br \/>\n<em>Are you sure you want to continue connecting (yes\/no)?<\/em><\/p>\n<p>To which the, answer is <code>yes<\/code>. Then you should see:<\/p>\n<p><em>Warning: Permanently added &#8216;<\/em>ipaddress<em>&#8216; (RSA) to the list of known hosts.<\/em><\/p>\n<p>Next up, should be a password prompt:<\/p>\n<p><em>root@<\/em>ipaddress<em>&#8216;s password:<\/em><\/p>\n<p>The default password (at least for iPhone v1.1.4) is <code>alpine<\/code> and, once this has been entered, umount should finally be copied to the iPhone:<\/p>\n<p><em>umount\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0100%\u00a0\u00a0\u00a015KB\u00a0\u00a014.6KB\/s\u00a0\u00a0\u00a000:00<\/em><\/p>\n<p>A few more commands are used to set execute permissions on umount, to do some Unix magic with mountpoints and then to copy lots of nothingness across both the partitions, as <a href=\"http:\/\/www.zdziarski.com\/papers\/wipe.html\">Jonathan A. Zdziarski<\/a> describes:<\/p>\n<p><code>chmod 755 \/sbin\/umount<br \/>\numount -f \/private\/var<br \/>\nmount -o ro \/private\/var<br \/>\nmount -o ro \/<br \/>\ncat \/dev\/zero > \/dev\/rdisk0s2; cat \/dev\/zero > \/dev\/rdisk0s1<\/code><\/p>\n<p>This will take a while (I think it was about 45 minutes in my case) and when it&#8217;s done, you should see a couple of I\/O error messages and a return to the shell prompt (#):<\/p>\n<p><em>cat: stdout: Input\/output error<br \/>\ncat: stdout: Input\/output error<\/em><\/p>\n<p>The iPhone GUI is also likely to be unresponsive (that is expected).<\/p>\n<p>So, with all data removed, I could put the iPhone into recovery mode once more to restore its factory settings and then jailbreak\/activate\/unlock it for the final time. After a test with the Vodafone SIM inside the iPhone to call my O2 SIM (in another handset) I had confirmed that the handset was successfully unlocked and ready for its new owner.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In some ways, this post is of limited value &#8211; as it&#8217;s for a first generation iPhone, running on iPhone software v1.1.4 &#8211; both of which will become old technology on Friday 11 July 2008.
