With the iPhone 4, Apple introduced the amazing Retina Display which gives us 4 times more pixels on the same screen size. Many app developers have already optimized their applications, including the icon, for the Retina Display, but there are still a few devs that are late to the game.
We already saw how to convert old app icons to Retina Display icons, but the process wasn't very straightforward. There is now an easier way to do all that thanks to a new jailbreak app...

More Apps Giveaway: Star Walk and Solar Walk

On this Black Friday, Vito Technology has some special sales going on for all their apps, and even a few of those to give away to some of you...
TinyUmbrella Updated for iOS 4.2.1 [Do it Now]
TinyUmbrella has been updated to allow you to save your SHSH blobs on iOS 4.2.1 for iPhone, iPod Touch, and iPad. If you are a jailbreaker and have 2 minutes to spare, I suggest you use it to save your SHSH blobs.
In case you don't know what TinyUmbrella is, it is a utility that allows you to save SHSH blobs, files that are necessary when you try to downgrade your iPhone to a previous iOS version. Without them, you couldn't downgrade. While most people don't care, it is especially helpful for jailbreakers...
That’s the Kind of Review You Want to Get for Your App
This is definitely the kind of rating and review that any app developer would like to get for his application.
I don't know what this app is. I just found this image accidentally on Twitter, via @rupinjapan. If you know the app, please let me know because it looks like it's definitely worth a download.
iPhone 4.2.1 UltraSn0w Unlock to Drop this Weekend
Some very comforting news on this cold Thanksgiving day, as MuscleNerd confirmed today that the iPhone unlock for iOS 4.2.1 will most likely be released this Sunday or even before.
This is good news, especially for those of you who still are using an iPhone 3GS or 3G. It is however not as good news for iPhone 4 users because there won't have an unlock for iPhone 4 for a little while...
List of Jailbreak Apps Compatible with iOS 4.2.1

Happy Thanksgiving
For everybody in the US, today is Thanksgiving, which traditionally has been a time to give thanks for a bountiful harvest. So I would like to take this occasion to thank you all on behalf of the iDB team to make this blog what it is today.
Hard work and original content are nothing without the people that make all this possible: you!
So thank you for allowing us to have such a great community around iDB. Thank you to iDB writers, readers, commenters, heck, we'll even thank the haters!
Enjoy the turkey :)
How to Backup Your Cydia Apps
One of the things I really dislike when updating my iPhone to a newer iOS and jailbreaking it, is reinstalling all my jailbreak apps, one by one. This is a long and tedious job, especially if like me, you have a bunch of tweaks and jailbreak apps.
There is now an easy solution to backup all your jailbreak apps, tweaks, and themes, so you can update your iPhone, jailbreak, and reinstall those apps in no time. Here is how it works...
The Difference Between a Tethered and Untethered Jailbreak
With the release of the RedSn0w iOS 4.2.1 jailbreak, the notion of tethered jailbreak has been reintroduced and there seems to be a little bit of confusion about what's different between a tethered and untethered jailbreak.
I've seen many comments asking more clarification about what a tethered/untethered jailbreak is, so I thought I'd give you a quick and simple explanation...
Apple Puts Yet Another Roadblock to Jailbreaks and Unlocks
Even though jailbreaking is now legal, the cat and mouse game will never stop between Apple and the jailbreak community. Last example is the fact that iOS 4.2.1 has introduced a new baseband requirement, as explained by Notcom, the developer of TinyUmbrella.
While it's not clear yet what Notcom means by "baseband requirement", we can nonetheless assume that it is some kind roadblock that's going to make it harder for us to jailbreak, unlock, and downgrade.
Here is what Notcom has to say about this new baseband requirement:
