How many people are unlocking the iPhone for use on unauthorized wireless carriers? There’s no exact way to tell, but numbers recently stated by AT&T in its quarterly earnings conference call are revealing.

AT&T says it ended 2007 with “just at or slightly under 2 million iPhone customers.” Apple recently boasted that it had sold 4 […]

We’ve received word that the a software-based jailbreak method for iPhone software/firmware 1.1.3 (enabling the installation of unofficial third-party applications) could be released as early as tonight or tomorrow. We previously reported on the existence of a hardware-based method and two software-based methods, one more straightforward than the other.

iPhone Atlas has now learned that one […]

While the iPhone still doesn’t support Exchange-sans-IMAP, Apple has posted a Knowledge Base document explaining how to set up a corporate mail server for IMAP so that you can use iPhone to retrieve your email from that server. Per the document “These key steps will need to be completed by the IT support team or […]

A clever hack from iPhone developer NateTrue lets you put speed dial numbers on iPhones running software/firmware 1.1.3. Here’s how it works:

Enter the URL: (phone number).tel.QLNK.net in MobileSafari then go to the page. This is a custom server from NateTrue that essentially makes bookmarklets out of the entered telephone number.
You’ll get a “Call” popup — […]

Several users are reporting an issue where mail sent from the iPhone simply disappears into the void, never reaching its recipient, nor appearing in the “Sent Items” folder, and also never generating an error message indicating that anything has gone wrong.

A few sample reports from an Apple Discussion thread discussing the problem:

“Sometimes when I compose […]

Developers have now completed an easier jailbreak method (refined from the previously noted software-based method), suitable for end users, that works with iPhones running software/firmware 1.1.3, iPhone Atlas has learned. However, developers of the jailbreak method are still debating whether or not to release the method publicly before Apple’s official SDK (software development kit) is […]

Here’s a minor usage tip for iPhone software/firmware 1.1.3: switching between multiple home screens doesn’t require swiping (or “flicking”) your finger across the display. You can also tap the area directly to the right or left of the small dots at the bottom of the screen.

As described by iPhone Atlas reader David Alford:

“As you add […]

Enterprise data plans for the iPhone are finally available from AT&T in the following packages:

$45: 200 SMS messages, unlimited data, visual voicemail
$55: 1500 SMS messages, unlimited data, visual voicemail
$65: unlimited SMS messages, unlimited data, visual voicemail

These new plans mean that enterprise customers have the, ahem, luxury of paying $25 more per month than consumers for […]

We previously reported on the development of a jailbreak for iPhone software/firmware 1.1.3, demonstrated in a video, that requires hardware modification. Now Jonathan “NerveGas” Zdziarski, developer of a NES emulator for the iPhone and a co-implementer of previous jailbreak methods, has claimed the existence of a separate, software-based 1.1.3 jailbreak that takes “about a half […]

The iPhone development community has done it again. Software/firmware revision 1.1.3 has been jailbroken (full read/write access to the filesystem), meaning that unofficial third-party applications can be installed under this release. Unfortunately, the current method is so complex that its developers have decided to hold off a public release [Update: We’ve also learned that the […]
