You've run the TIFF exploit jailbreak and your iPhone or iPod touch now has Installer.app on your main page. So now what? Here are some tips and ideas for you.

Add Community Sources. Most third party applications are found under Community Sources in Installer.app. Until you add this feature, you won't see most of the dozens and dozens of available applications from repositories like SMXY and Conceited Software.

Try out some great apps. My personal favorites include my own Voice Notes recorder (for iPhone only), Apollo IM instant messaging client, and Mobile Colloquy for irc. There are productivity apps, games, and utilities, all available for your mobile device.

Add direct file access. Install the BSD subsystem and (in Community Sources) Open SSH (both from NerveGas). Once you've installed ssh, you can use any sftp client to transfer files onto and off of your unit. On the Mac, you can also install MacFuse and sshfs to gain Finder access to your units. Remember that the new iPhone and iPod touch 1.1.1 password is "alpine", not "dottie". Many GUI sftp clients may not see the entire directory tree. In this case, you may want to enable afc2.

Know when things go wrong. The latest Installer.app has been hammered by new users. If you get a "package" error when trying to install, just do a re-install. You may need to uninstall first, depending on the progress when things failed. If you touch an app icon and it launches, pauses and quits, make sure you've installed the BSD subsystem. Failing to install BSD is the number one reason most app launches fail.

Know about restoring. If you ever change your mind about a jailbreak, just restore your iPhone or iPod touch using iTunes. Assuming you haven't unlocked, your iPhone or touch will be identical to one shipped from a factory.

When things slow down A number of people have reported system slow-downs after jailbreaking. Unfortunately, a roughly equal number have reported the same problem without jailbreaking. If this happens to you, just restore your iPhone or touch and re-jailbreak.

OMG, OMG, OMG restore failed This isn't that uncommon. Try restoring again once or twice. If iTunes fails to see the iPod or iPhone, google for iphuc dfu mode.

Although I knew that the 1.1.1 firmware update introduced more attachment viewing support, I didn't realize until now that it added AMR playback. AMR, if you don't recall, refers to Adaptive Multi-rate Compression. It's the audio data compression format used by the iPhone for both voice memos and (if you've installed my Voice Notes application) voice recording. AMR is used primarily to store spoken audio.

So why is this big news? Well, if you're very very patient and you don't mind waiting for long gaps within a conversation, you can now use your iPhone as a very low-end push-to-talk device. By this I mean, you can install VoiceNotes and use it to record short messages. You can then email those short messages to a friend and they can play it back on their iPhone. To respond, they do the same: record and email.

This is obviously a long way from VOIP but as a stop-gap measure it works pretty well. I tested out a voice-only conversation the other evening and, while slow, the recording and playback quality was just fine for communicating.

Right now, the slowest part of the process involves addressing the message in Mobile Mail. If people show an interest, I'm considering either updating VNotes or writing an app that allows you to add the recipient's email once and then handles the addressing bit. Let me know in the comments.
