Wiping An IPhone (more Thoroughly)

June 10, 2008 by 7 Comments


You may be hoping to subsidize the purchase of an iPhone 3G with the sale of your old one, but since you should wipe all your personal data from the old one first, we brought you [Rich Mogull]’s method for wiping all your private data off of an iPhone. The method, which involves overwriting your data with music, is slightly flawed, mainly because of live files that can’t be deleted while the phone’s OS is working and because the OS reserves a portion of the hard drive as unwritable space, which will make it impossible to completely fill it with music.

For those looking to annihilate every scrap of personal information, check out [Jonathan Zdziarski]’s method. It involves restoring the phone as a new phone, then jailbreaking it. Once the user has shell access, umount is used to force the two mount points into read-only mode. Now the partitions can be overwritten with /dev/zero, which should wipe them clean. The phone should then be forced into recovery mode to perform another full system restore, and the process is complete. As [Zdziarski] notes, several iterations of the process with /dev/random should prevent even NAND recovery, but there is an even better way of ensuring full data destruction: “simply take a sledgehammer to the device.” If you are unfamiliar with the command line though, chances are [Rich Mogull]’s method will be easier for you to handle, but don’t blame us if you sell your phone and the Feds get wise to the evidence you left on it.

Location Aware Task Tracking

June 10, 2008 by 2 Comments


With the iPhone finally getting legitimate GPS we’re bound to see more widespread use of location based apps. Services like Dodgeball, Brightkite, and a few Twitter clients have been around, but failed to tightly integrate with the hosting phone. Now we’re seeing applications that reach beyond just “finding your friends”. [Merlin Mann] directed us to the version of OmniFocus for the iPhone. OmniFocus is a task management system that’s now location aware thanks to the iPhone. This means it knows to show you your grocery list while you’re at the store and work tasks while you’re at work. Passive interaction could really make similar systems a lot more enjoyable to use.

We think this is just the tip of the iceberg. Imagine alternate reality gaming that gives you a virtual map while you navigate the real world. Geocaching, road rallies, and scavenger hunts could have a running narrative displayed as you progressed. Using technologies like GeoRSS will let us pull data back into the real world making that rare trip outside a lot less painful.

New Vs. Old IPhone Apps

June 10, 2008 by 16 Comments


You’ve probably never heard of this obscure new device called the iPhone 3G from no-name manufacturer Apple, but we decided to give a rundown of some of its newest apps anyway. We’ll be comparing them to non-SDK third-party apps that only work on jailbroken iPhones.

Hackit: What To Do With A 1st Gen IPhone?

June 9, 2008 by 34 Comments


There’s a new iPhone 3G coming out in July. If that statement shocks you, you might want to check your connection. We love new shiny hardware, but what we’re really interested in is the number of “old” iPhones that are going to be hitting the market. Many people will be ditching their 1st generation iPhones just to get GPS and 3G. This abundance plus the new $200 price tag is bound to depress the price for used phones.

A used 1st generation iPhone is actually a pretty attractive device. It’s already been laid wide open by hackers so you can run pretty much anything you want on it instead of waiting for the App Store to tell you what you can and can’t do. You could use it as a WiFi Voip phone, a simple web pad, run an NES emulator, use it as a musical instrument, or build an army of robots.

What will you do when the price of used iPhones bottoms out?

IControlpad, IPhone Gamepad

May 24, 2008 by 7 Comments

[CraigX] has been dabbling in iPhone accessories lately by adding a gamepad. Called the iControlpad it surrounds the iPhone making it look very PSP like. As anyone who has jailbroken and installed emulators probably knows, without feedback the touch screen based buttons are less than great.

The unit is currently a prototype however there are plans to produce and sell the units. They have received support from Zodttd, an organization that has created iPhone apps like snes4iphone and genesis4iphone. The developers also state they’ll provide source and SDK support. The sparse development blog announces their success using a hacked up SNES controller over the docks serial connector, but they provide absolutely no details.

Erase An IPhone Properly

May 20, 2008 by 14 Comments


A fundamental problem with flash memory has just gone mainstream. A detective successfully recovered data from a refurbished iPhone purchased from Apple. Flash memory controllers write to blocks randomly so using standard secure erase techniques are no guarantee that all of the storage space will be written.

[Rich Mogull] has posted a method that should wipe out almost all remnants of your personal data. You start by restoring the iPhone in iTunes and turning off all the syncing options. Next you create 3 playlists large enough to consume all of the phone’s storage space. Sync each playlist in turn and your residual personal data should be obliterated. All that’s left to do is sit back and wonder when the first article about the MacBook Air SSD being impossible to securely erase will be published…

Free Your IPhone

August 26, 2007 by 25 Comments


I wasn’t going to post this – it’s a freakin phone after all. But I’ve gotten quite a few tips on it, and I’d like them to end. [George] made a concerted effort to hack the iPhone – and it paid off. After his crazy ebay auction that topped out at 99,999,999.99 last time I checked, he ended up trading his first phone for a Nissan 350z and a few more iPhones.
He documented his process, step by step – if you’ve got the skills, you can probably do it yourself. The soldering work is damn fine work – probably the hardest thing there is. The write up is a little hard to follow, so plan on taking some time to comprehend everything. (Blogging software isn’t the best way to organize how-tos, trust me on this.) My hats off to [George], he did some great work. – So, why didn’t I want to post it? All this work yielded one thing: carrier choice for the iPhone.
