iPhone 4G rumors are hot these days and every few days new concept images gets published on internet, here we have another set of freshest rumored leaked iPhone 4G images :

Cydia - the iPhone application which allows users to browse and download unofficial/unapproved iPhone applications, themes, ringtones and mods on their jailbroken phones is a must use if you intend to enjoy the full potential of your iDevice in ways Apple does not allows you to do by default.

If you are missing the Cydia fun because you don't have a working data plan or Wi-Fi connection on your iPhone or simply because it's a pain to use it on the phone, here we have an awesome utility Cyder II which allows you to browse, download, manage and synchronize data with Cydia from your desktop computer.

Hactivating your iPhone does have it's side-effects and one of them is that you are not able to use iPhone Push Notifications, the problem arises because Apple identifies devices via unique certificates and validate them on PUSH servers - However, this problem is now been taken care of by new Cydia application "Push Doctor" made possible by it's creator anethema who has found a way to generate these unique certs en-masse to supply a proper fix for all the hacktivators out there. Installing the app will simply download and inject unique certs into your phone's keychain making them uniquely identifiable by PUSH servers enabling the functionality properly.

If you have Wi-Fi or internet connectivity on your iPhone it's pretty easy to install carrier unlock Ultrasn0w via Cydia on your device, however, things get complicated if you have no internet or Wi-Fi available on your iPhone leaving you with no choice but to install Ultrasn0w manually which require working with iPhone file-system and file-permissions.

Thankfully, we do have a pretty much unknown utility 'UltraPusher' which lets users install MobileSubstrate and Ultrasn0w on their iPhone offline from any windows computer, all you need to do is to connect your phone via USB and let UltraPusher inject the required files automatically.

Sn0wBreeze 3.1.3 update is now available for download allowing users to create custom 3.1.3 IPSW restore files while retaining the older baseband so they can still enjoy existing blacksn0w or ultrasn0w iPhone unlocks.

To get iPhone OS 3.1.3 with jailbreak and carrier-unlock all you need to do it to create a custom IPSW file using Sn0wBreeze 3.1.3 (download link after the jump) and restore you iPhone with this newly created IPSW file having older baseband.

There is nothing exciting or worth upgrading in iPhone OS Update 3.1.3 but if you still want to upgrade and keep the jailbreak it is now very much possible thanks to updated redsn0w 0.9.4 utility by iPhone Dev Team, do keep in mind if you are using an unlocked iPhone do not upgrade as no unlock is yet released for iPhone OS 3.1.3.

After pushing the iTunes 9.0.3 update yesterday Apple today released the iPhone OS 3.1.3 for iPhone and iPod Touch users, the latest update to iPhone firmware offers basic bug-fixes and stability improvements as detailed after the jump.

Install0us is one of the most easiest and popular way to get pirated iPhone applications and games but not anymore as the developer of Install0us will be shutting down the application and repository facing legal threats, according to the Install0us developer puy0 he was under the wrong impression that since Install0us was offering same services as other installer apps : browse / download / install, without providing any links to cracked materials he had something legal and legitimate to offer but after having a conversation with a copyright lawyer recently he is now convinced that it is indeed illegal to share someone's hard-work this way and he might end-up facing a legal trial for this - so Install0us has started to shutdown it's doors as servers got offline one after another.

Much needed utility for creating custom IPSW files on Windows Sn0wbreeze 3.1.2 Final is now available for download, Sn0wbreeze 3.1.2 Public Beta download shared earlier had Expert Mode disabled but the final version has it enabled which lets users create custom IPSW files with options including changing of boot and recovery logos, enabling verbose boot mode, download and add applications packages, include blacksn0w or Bootneuter unlock, add Cydia and Rock installers, pre-hactivate the phone, make IPSW NOR only and change root partition size.

Sn0wbreeze lets Windows users create customized iPhone/iPod IPSW restore files having their personal selection of applications and customizations to be pre-compiled into the restore file so they can restore as many devices as they like to a fixed configuration without working individually on every device.

Just moments ago iPhone Dev Team released the redsn0w 0.9 public beta download for Windows and Mac, supporting the latest iPhone OS 3.1.2 the cross-platform jailbreaking and unlocking utility for iPhone and iPod Touch also supports customizations like changing of device boot logo, recovery logo, and allows users to switch on “verbose” booting mode.

The free standalone utility does not use iTunes and no custom IPSW's are involved in the process, the current beta supports all iPhones and iPod touches except the iPod touch 3G having Apple firmware 3.0 and 3.1.2, direct download links are at the end of this post.
