Just bought a 2nd hand iPhone 3GS hoping to use it with my T-mobile sim card. I believe the phone is running 4.0.2 (how exactly do I check the firmware without a SIM card in the phone)? I've searched the web and there doesn't seem to be any software for unlocking this particular firmware version? Please help, thanks!

Nop, there's no way to unlock 4.0.2.

Yea. I've been trying to downgrade to 3.1.3 but getting "Error 3194" in iTunes...searched the web and there's no solution to that error either.

I'm just about to throw in the towel and wait for someone to release a 4.0.2 unlock; when will that be?

Um, I'm not sure I know it was a few weeks after iOS 4 was released they had a JB and Unlock. So with 4.0.2 released a few weeks ago, I'd say soon? I'm not sure. Should also read up on the new Patents that Apple is trying to get for JB phones. Just keep checking that site for updates, I can't imagine it would be much longer. All the instructions are on the site too, so it's easy to follow.

Thanks. I also want to make sure that it really is running 4.0.2, how do I check that without a SIM card in the phone? There's a "secret code" (#3001#1234...or something) that I tried but didn't work?

Did you do the update already through iTunes? If you have it should still allow you to access the phone with the T-Mobile SIM. If nothing else plug the phone into your computer and open iTunes. It should show you in the Info tab of your phone. Under Version it should say which version you are currently running.

You'll need a AT&T sim card to activate it though. As the jailbreaks all seem to not activate only jailbreak.

Yea, I used my ATT Sim, even if the SIM Isn't active it will still activate the phone. But for some reason when I did it, It wouldn't activate when the phone was plugged in, after I unplugged it it would activate? But yea you will need an ATT Sim then you can put the Tmo SIM in after it's activated.

I will be able to jailbreak & unlock a 4.0.2 iphone with no SIM card in it, right?... Programs like jailbreakme all require that the phone is operational and can install software, but obviously that's not possible with no SIM card...

Well if the phone is/was already activated just put your SIM in and run thru the JB process and then once that's done then do the Unlock. From what I've heard you do need the phone activated before doing the JB or it will fudge up. But at the same time, like I said, the phone wouldn't activate for me while plugged in even with a ATT SIM in. Unlock can be done/should be done over wifi not over Carrier Network.

People seem to get confused about something. Jailbreaking and unlocking are NOT the same thing, and are pretty much unrelated.

I wouldn't say unrelated.. you need to Jailbreak the iPhone to be able to perform a sim unlock. I understand people get the two things confused a little sometimes but they are both important in the unlock procedure.

@OP: If you didn't update to 4.0.2 you would of been fine :wacko:

    • Snap Inc. launches new SPECS augmented reality glasses (for 'just' $2,195)

      By Aditya Tiwari · Posted

      Snap Inc. launches new SPECS augmented reality glasses (for 'just' $2,195) by Aditya Tiwari Image: Snap Inc. Smartglasses powered by augmented reality are the latest fashion because the smartphone market is slowly reaching saturation. Snap Inc. announced its latest AR-powered smartglasses, called SPECS, that aim to strike a middle ground between underpowered AI glasses and heavy headsets you can't wear all the time. Available in two sizes, Snap SPECS are made from high-performance Swiss TR90 polymer and feature removable inserts to support prescription lenses. Its 47mm model weighs about 132g; the bigger 52mm model weighs 136g. Snap Inc has been spreading the word about the new glasses for a while now. Earlier this year, it even spun off its smart glasses team into a subsidiary called Specs Inc. Its proprietary LCOS (Liquid Crystal on Silicon) display delivers a 51-degree field of view and 16 million colors. Snap says the device gives the feel of a 24-inch desktop monitor when you're working, and of a 115-inch home cinema screen placed about 10 feet away when watching a movie. A pair of custom stereo speakers and 6x high-SNR MEMS microphones are built into the temples of the smartglasses to deliver open-ear audio while you cast a screen, stream content, open a whiteboard, or collaborate with others. Snap Inc. patted itself on the back, saying the smartglasses don't need tethering or a puck to connect to a computer. Under the hood, SPECS draw its power from two Snapdragon processors: one for computer vision and another for running Lenses. The device supports fast hand tracking, low latency, and responsive interactions that help digital content feel anchored in the real world, according to the company, which claims that SPECS can "deliver 7-millisecond motion-to-photon latency." The smartglasses offer up to four hours of battery life on a single charge while providing AI assistance, Bluetooth notifications, Lenses, audio/video playback, and more. The battery life could jump to 20 hours of mixed use when the charging case is included. Image: Snap Inc. You can view and interact with AR Lenses anchored directly to the physical world around you, and an on-board AI assistant uses the camera to see what's around to answer questions or provide real-time help with tasks. Snap Inc. noted that it filed more than 7,000 patents during the development of SPECS. It's trying to build the required digital ecosystem around the smartglasses, and said that developers have already published hundreds of Lenses for SPECS. Moreover, their electrochromic lenses use the same technology available in Boeing 787 Dreamliner windows, enabling them to shift from clear to tinted in just 10 seconds when you walk out of your house. Snap SPECS are now available for pre-order on the official website with a $2,195 price tag ($200 refundable deposit). The smartglasses are expected to ship in the US, UK, and France during the Fall this year.

      Sound Booster 1.13 Build 575 by Razvan Serea Increase volume on your laptop. Boost the volume of even very quiet speakers. Raise volume above maximum. Letasoft Sound Booster can be used as an extra amplifier when the volume of the program you are listening to is too low for comfortable listening and you feel that your PC’s speakers can produce a louder sound. This can be the case when the audio or video has been recorded at the level below normal. Or, for example, when the other person’s microphone you are talking to on Skype, is not working properly. There can be a plenty of other reasons why the sound is being too quiet and there is not much you can do about it except buy external speakers. Sound of any application that is being played in the system can be amplified up to 500%. Letasoft Sound Booster can raise volume of programs like web browsers, on-line communication software (Teams, Discord, Zoom), any kind of media player or games. Simply put, volume of virtually any program that can play any sound in PC, can be boosted to a comfortable level with Letasoft Sound Booster. You can control current volume with the pop-up slider from the system tray. Alternatively, you can assign system-wide hot keys for increasing and decreasing, and use them when you need to adjust volume Letasoft Sound Booster constantly monitors current gain level and prevents samples from clipping, thus reducing all major sound distortions.

      I own these and the normal QuietComfort ones from Bose. The QC are amazing and I want to love these, but for the life of me, I have a terrible time getting them attached to my ears.
