George Hotz, the first to develop an unlock for the iPhone 3GS has released an updated unlock for the device.

However, there are some caveats such as the lack of support for “hacktivation” and some minor improvements are coming soon to the App. Your iPhone 3GS must be already Jailbroken using either QuickPwn, Redsn0w or Purplera1n.

Any iPhone 3GS users who are looking to easily share a video over Twitter should look no further than TwitVid. The app, which was recently released does one thing, and does one thing well — it allows iPhone 3GS users to share a video on Twitter.

The videos can be one that you have already recorded and saved on your iPhone or a new video that you have yet to record.

Of course, due to the video functionality, this app requires users to be on an iPhone 3GS as well as running OS 3.0. Best of all, the app, which is currently available, is free of charge.
Additionally, TwitVid can also be used directly from the web at TwitVid.com. The main difference (aside from not being an iPhone app) is that users of the website can also share the video to Facebook, MySpace and YouTube at the same time.

In Canada and looking for a nice deal on an iPhone 3G? If that is the case, you may want to check out the latest offer coming from Fido.

They have both 8GB and 16GB “refreshed” iPhone 3G’s for either $49 or $99 respectively. According to the details on the “refreshed” iPhone’s;
iPhones are preloaded with current software and have been extensively and independently quality tested.

Some refreshed iPhone 3G devices will have final scratches.
Refreshed iPhones carry a warranty of 6 months from the date of shipment.
Basically, it seems that these are models that have been returned from other customers within their 15 day return period. It should also be pointed out that these phones are noted as not coming with any accessories.
Finally, in order to get this pricing, you will be required to sign the standard three year agreement.

In our previous articles, we have covered the specifications of  Apple’s new iPhone 3GS and it was no secret that Apple’s new iPhone 3GS is a faster version of iPhone 3G.

With a list of iPhone applications being used on both the iPhones, the iPhone 3GS comes out as a clear winner. Because of the repeated usage of the listed applications, the available RAM of iPhone 3GS has dropped down to about 122 MB. The Safari browser was still running on iPhone 3GS when this drop was noticed.

The speed of iPhone 3GS is attributed to other factors as well but the clear comparison of available memory in both iPhone 3GS and iPhone 3G goes to show the significant impact that increased RAM has made in Apple’s latest iPhone.

It seems there may be a line being drawn between the Dev Team and Geohot when it comes to working together to bring what is best for the end user as a whole. While some may argue that them working together is for the best, I would argue that competition between the two may end up bringing the end user slightly better tools.

Of course, my opinion is just that — my opinion. However with that, Geohot has recently released his own solution for unlocking the iPhone 3GS which has been dubbed purplesn0w. And yes that means we have yet another strange name to remember when it comes to iPhone hacking tools.

Anyway, purplesn0w is the “geohot 3GS unlock solution” and is noted as being able to help prevent you from worrying about “Wifi fails? Battery fails? Unlock fails?” after you unlock.
Basically, what purplesn0w will do is unlock your iPhone 3GS after you have already jailbroken it using purplera1n. According to Geohot, purplesn0w is;
“A soft unlock for your 3GS that I’d actually use day to day. It’s not a daemon that takes any resources, and it doesn’t add a task to your baseband. It’s very close to a true unlock. All it does is patch three files, CommCenter, lockdownd, and your wildcard activation plist(which you need, activate w at&t sim first, no hacktivation support yet). That’s it, no other files are installed.”

As always it is suggested that you back up your iPhone before beginning, but otherwise here are the steps you need to follow in order to use purplesn0w. Keep in mind, this is also assuming that your iPhone 3GS is already jailbroken.

Be sure to have legit activated 3GS
Disable 3G if you don’t have it(like T-Mobile).
Add apt.geohot.com to Cydia
Install com.geohot.purplesn0w
Watch for success output in Cydia
Reboot, and enjoy your unlocked iPhone

You can save $20 on the $99 8GB iPhone 3G if you’re willing to forego factory freshness—refurbed models are $79 with free shipping from AT&T.

They don’t have refurbed data plans for discount, do they; that’s what we really need.

It seems the discount on previous models of the iPhone is on, and AT&T is looking to clear out all of the previous incarnation of the iPhone from their inventories. This is good for the consumer, but might it also lead to a flood of requests on AT&T’s already strained network from new customers, who previously couldn’t afford the phone?

Hopefully, AT&T is getting their network prepared, and we won’t see a huge slowdown for existing customers.

The site doesn’t say whether this is a temporary sale or not (it probably is permanent, more than likely), but those that don’t think the new 3GS is all that should go check this out ASAP.

German GPS firm Navigon has begun branching out into North America with its release of MobileNavigator North America Lite, available for free.

Readers should note that the free lite version does NOT offer the active route guidance most users are looking for in a GPS mapping application, although it can display a user’s position on its map and locate nearby points of interest. Full turn-by-turn functionality will be available in a future paid version.

Navigon released the full

version of MobileNavigator Europe at an introductory price of $94.99 in late June, but the application is currently priced at $139.99. Navigon is one of the larger players bringing turn-by-turn GPS solutions to the iPhone, with AT&T opting for the same subscription service used on other platforms and TomTom embracing a forthcoming hardware/software combination solution also competing for users’ attention.

It seems GPS companies love the iPhone suddenly, and plan to embrace the platform in many future software releases.

One of the more overlooked features of the new iPhone 3.0 is support for a new open standard for live video streaming over HTTP, which promises to open up standards-based video broadcasting to a wide audience while giving mobile users an optimized picture as they roam between WiFi and mobile networks.

At the March unveiling of iPhone 3.0, Apple only dropped a subtle hint about new streaming video features in the new operating system (literally limited to writing “streaming video” on the slide of other features, below), leaving out any details about how it would work and not even mentioning the feature in any detail in the presentation.

The technology behind HTTP Live Streaming leaked into public knowledge in May when Apple submitted it to the Internet Engineering Task Force (IETF) as a draft standard on track to become an RFC (or Request For Comments, the memorandum used by the Internet Society

to define how technologies work in order to foster cooperation and compatibility between the vendors implementing them).

Apple’s HTTP Live Streaming proposed draft looks a lot like a method Microsoft began selling last year, called Smooth Streaming. The difference is that Apple’s proposed IETF standard can use anybody’s encoder and broadcast server, and will work with any client software designed to receive the stream. In contrast, Microsoft’s Smooth Streaming is of course designed to exclusively use Microsoft Expression Encoder, Microsoft Internet Information Server with a Smooth Streaming extension, and requires Microsoft’s Silverlight 2 on the client.

Essentially, Apple wants a standard for streaming video that anyone can use so that it can continue selling hardware without being either shut out of the market by proprietary software, or held captive by it; Microsoft, as a software vendor, wants to create another captive market where it has the power to shut out competitors at its whim.

Fortune reports that Apple retail store stocks of the 16 GB white iPhone 3GS model have fallen precipitously low early this week. At present, only 10% of Apple’s over 200 retail stores have the model currently in stock.

if Apple just isn’t making enough of them.

Most Apple retail stores currently have both the black and white 32 GB models available, while the black 16 GB is available in only about 35-40% of stores.

In late June, Apple posted an online availability tracker for the new iPhone 3GS, updated hourly with stock levels at each of its retail stores. Supplies of many models tightened early last week, but rebounded later in the week, and we’re expecting the same here. Early next week things should look up.
