The iPhone 4S has been a hit among Apple fans with its new fast flash features, but many have been looking for a jailbreak that will allow them to customize their phone to the fore. The lastest iPhone jailbreak and unlocking software is out, according to bestunlock.com.

The company have launched their latest jailbreak for the 4S and are urging people to download it to have the desired flexibility on their phones. Jailbreaking is generally risk-free, according to Best Unlock. It only adds features to a mobile phone that is otherwise fixed on the exclusive Apple functionalities. With a jailbreak you can download apps that you would not normally be authorized to at the Apple Store.

Through unlocking and jailbreaking their phones, past customers have been able to obtain free GPS Navigation application; zero roaming charges for overseas calls; enabled video chat on 3G and 3Gs iPhones; as well as having the Cydia application installed, according to the Best Unlock website.

I had lots of questions regarding the validity of this software, and they were all answered in minutes. After downloading the software, it was a painless two-minute process. I thoroughly recommend this, Martin McG of the United Kingdom says of the Best Unlock iPhone unlock software.

The following iPhone software's can apparently  be unlocked and  jailbroken: iPhone 4.1, 4.2, 4.2.1, 3G 3Gs and iPhone 4 4.3.3-4.3.5/5 . Visit: www.BestUnlockiPhone.com

 Meanwhile, an unlocked version of the iPhone 4S is set to go on sale in November according to Apple's Web site, but since the release of the contract phone there have been reports of unlocked phones circulating certain retailers across the U.S.

Stephen Troughton-Smith has verified buying an unlocked version of the phone from an Apple Store, rumor site 9to5mac.com reported. Apple clearly states on its Web site that unlocked versions of the phone can be purchased in November, priced at $649 for the 16GB, and $749 and $849 for the 32GB and 64GB, respectively.

The unlocked phone mentioned in the report came with an AT&T simcard, but when Smith plugged the phone computer and launched his iTunes account he was presented with a message telling him his phone had successfully been unlocked and he later found that it worked with a T-mobile sim-card.

Should this report be true, it could be good news for those who spend excessively on international roaming charges and are tied down to AT&T's World Traveler Service, priced at $6 per month.

Meanwhile, Sprint has shipped the first batch of its iPhone 4S unlocked. The Sprint iPhone 4S will ship with its micro-SIM slot unlocked. However, it'll be locking that slot shortly after launch via an update pushed to those devices. After the slot has been locked, Sprint says that it'll allow customers in good standing to unlock the SIM for international use in the future, Sprint spokeswoman Michelle Leff Mermelstein said in a statement.

The Newest Features on the iPhone 4S:

The A5 Chip: The new iPhone may have the same retina screen but the interior has had an entire revamp with the latest A5 chip making its way into the phone.

It's Fast: With a Dual-core CPU the new iPhone is 2x as fast at CPU tasks and up to 7x faster than the previous iPhone, which is a great perk for games. Data can also be downloaded twice as fast as before. Theoretical max performance used to be 5.8 up and 7.2 down - now doubles to almost 14.4Mbps down.

Second Wireless System: The new iPhone can now intelligently switch between two antennas to produce even higher calling quality. This has never been done in a phone before.

New Lens: The brand new camera lens has five elements and goes down to a wide f2.4 aperture

Apple designed ISP: The ISP enables face detection in photos and lets in a lot more light while shooting.

HD Video: The new iPhone 4S camera comes with stunning HD video with 1080p real-time video image stabilization.

Intelligent Assistant: With the new iPhone you can actually talk to your device through an integrated intelligent assistant who gets things done just by asking. What is the weather like? Where is this restaurant? Your device gives you all the answers you are looking for. Compose and dictate email right to your device. Set timers. Look up contacts, create notes, and search the Web.

More Languages:  The intelligent assistant will have built-in with support for English, French, and German. More languages will be added over time.
