Q: How do I add the needed repository in Installer?
A: 1) Once you are using the latest version of Installer app (Version 3.0 beta), install Community Sources, then go to Sources at the bottom right, Click edit at the top right corner, and then click add at the top right corner and type in this url: http://sleepers.net/iphonerepo. After adding it, hit Refresh at the top left.
There isn't a Safari Plugin yet for version 3.0 at the moment.
2) If you are using the old Installer 2.0, you can just enter the url in Safari, since there is a plugin.
Note: You must add this source to find the virginize scripts and Anysim 1.1 in Installer.
Q: So I am done jailbreaking, activating, and unlocking, now what?
A: First thing to do is go back into Installer and install Community Sources, BSD Subsystem (if you haven't already), and Summerboard. Installer is your main source of 3rd party applications. A good read: at TUAW
Suggested apps: wedict + merriam webster dictionary, iblackjack game, labyrinth game, sodoku game, pushr (send photos to flickr acocunt), sendsong (make ringotnes), Apollo IM (IM), colloquy (irc), navizon GPS, mobile finder (file manager), mobile todolist, sketches, customize, and services. These apps have been tested to work in 1.1.1.
Q: Why is Customize so buggy on my 1.1.1 phone?
A: If you are using 1.1.1, do not mess around with the image changing option in Customize app, it could severely mess up your iphone to the point of restore. You can use rSBT(icon location) within customize though.
Q: What does Summerboard do?
A: Summerboard allows you have pages in 1.1.1 and also allows you to change themes and how the homescreen looks.
Q: The earphones that came with the iPhone suck! What can I do?
A: A little fact: your iPhone earbuds is a REMOTE also! Click the little mic once to pick up or disconnect a call. When playing music, tap it once to pause, and tap it twice to skip to the next song.
You can also replace the buds of the earphones and retain the mini remote. More Info.
Q: How do I get free ringtones on my iPhone?
A: On both 1.02 and 1.1.1, you can use Sendsong app to send a song to ringtones. After a sync, you must go back into Sendsong and click a song and click Post-sync restore.
Another method can be found at Hackint0sh which does survive syncs.
Q: What do you recommend as a case?
A: I don't recommend any cases, but films that will protect the front and back from scratches and smudges. High quality ones can be found at Guardfilm.com. Make sure to use the exact amount of water and soap asked for. This film is great because it feels good, looks like there isn't a case, and prevents smudges!
Q: I Installed openSSH, what does it do?
A: openSSH allows you to use WinSCP or terminal to SSH into your phone. If you installed openSSH, make sure to use either usbtl or Services app to turn off SSH when not in use, SSH will drain your battery.
Q: After running jailbreakme.com on my 1.1.1 iPhone, my youtube doesnt work!
A: Please read this page to fix that.
Q: After virginizing my old 1.02 iPhone, updated to 1.1.1, the jailbreakme.com method doesn't work!
A: You may have to do a full restore on the iPhone again. Many users report that it doesn't work after the initial update, but after a full restore, it works. If that still fails, restore again, and use one of the alternative jailbreaking methods.
