I'm an iPhone 4 user, what should I do?If you have not already, make sure you save your iOS 6.1.3 SHSH blobs with iFaith, TinyUmbrella, or redsn0w (ipsw required). There is a lot of confusion about having to be running iOS 6.1.3 to obtain such blobs. No, that requirement only applies if you're dumping blobs right off the device. Which also makes me mention, if you have a firmware below 6.1.3 and do not have SHSH blobs for it, make sure to grab those blobs with iFaith. If you obtain these SHSH blobs, you are free to upgrade to iOS 7 and downgrade back down in case of anything getting released (DOES NOT APPLY TO A5 USERS).
I'm using a device with an A5 processor or higher, what should I do?
Why? There is currently a possibility of a potential 6.1.3/6.1.4 untethered A5+ jailbreak being pushed in the upcoming days/weeks.
If you're jailbroken on 6.0 --> 6.1.2 with evasi0n, you're better off staying where you are.
It is worth staying on 6.1.3/6.1.4 while iOS 7 is out if you want the chance to jump on board the potential A5+ 6.1.3/6.1.4 jailbreak. Once an iOS 7 jailbreak goes public, then you should have no concerns about the upgrade.
Also, although many people find it "useless" to save A5+ SHSH blobs, you're not going to lose anything by connecting your device and clicking a button. The saying is "Better safe, then sorry!". If some sort of low level boot loader exploit or apticket loophole goes public, such A5+ SHSH blobs will become useful again. (It is also worth noting that it is currently useless to look into 6.0 --> 6.1.2 A5+ downgrading due to Cydia caching incomplete aptickets. Read more). As usual, you can save A5+ shsh blobs for 6.1.3/6.1.4 by using either iFaith (click Show available caches on server and follow prompts), TinyUmbrella, or redsn0w (ipsw required).
Who should I follow for updates for the potential A5+ 6.1.3/6.1.4 jailbreak?@winocm
Please refrain from asking for any "ETAs", updates, etc. other than what is already posted.
Who should I donate to for an A5+ 6.1.3/6.1.4 jailbreak/BETA?!No one. If you have donated to a non-credible/random dude who claims to be working on a jailbreak, demand a refund or issue a dispute on your credit card/PayPal. Any credible "jailbreak dev" will not ask for donations in advance to create a jailbreak.
Are you going to release an update to sn0wbreeze/iFaith so I can preserve my iPhone 4 baseband when upgrading to iOS 7?!Yes. Probably sometime this weekend. (Should be able to work on it while in line for the iPhone 5S).

Have an A1 day! ;)
Update #1 (September 20, 2013): Apple seems to finally closed 6.1.3/6.1.4 signing windows for devices capable of running iOS 7.
