I jailbroke my iPhone, now what should I do?

So I jailbroke my iPhone 4, Cydia installed fine and everything. I tried downloading some files from Cydia, but it says that they require other files that I need to install, but I can't find them. Can someone give me some basic starter things I should download with Cydia? The more detailed the description the better. And also some fun things too please.

  • Jailbroke iPhone, now NO signal on ANY network? Cydia, iOS 6.0, 3GS? I jailbroke my iPhone purely because I want to unlock it to all networks (I live in Australia and it's a British phone). I used evasi0n and now I have Cydia installed on the phone. I also installed ultrasn0w from Cydia app store. Not only does the phone not work with my Aussie SIM card, it now no longer works with the Original simcard (it was working fine before the jailbreak).It just says "searching" and then eventually "SOS only". Any help tech experts?
  • If I previously jailbroke my iPhone 4, will AT&T deny my request to unlock it? I jailbroken the phone this year(I think when iOS 5 was released). But ever since a certain patch update, the jaibrake feature disappeared. I was always too lazy to re-jailbrake it again. So my question is, even though my iPhone was previously jailbroken, could AT&T deny my request to unlock it? http://www.att.com/...DezkUSSyYu
