Sleeping Bags

Someone was asking me about sleeping bags. Good reviews are at “Outdoor”: and they have some good synthetic bags including Mountain Hardware UltraLamina 32 for $175 and a three season synthetic bag from North Face called Cat’s Meow.

Then there are some bags that are ultra lightweight. For instance, the REI Kilo Flash +40 at $179 is a 750 fill bag that weighs 1.2 pounds if you can believe it.

Guide to unlocking iPhone to 1.1.2

The state of the world for “iPhone”: firmware is very confusing. The things to understand is that there are three parameters, the version of your firmware (1.0.3, 1.1.1, 1.1.2 and the new 1.1.3) and different versions of the firmware that run the GSM baseband chipset (4.01.xx and 4.02.13_G) and different boot loaders (BOOT03.09_M3S2 and BOOT04.06_M3S2). So here is the current as of January 13th state of affairs:

* Firmware 1.1.3 is just out and you shouldn’t upgrade to it. It bricks your iphone. Just “announced”: and is a pretty big release. It lets you send SMS message to multiple people (not a big deal, there are third party updates to the text program that do this), Goog Maps can now show your location by cell tower triangulation, you can drag and drop icones to your home screen, the home screen shows paginiation and you can add web bookmarks to your home screen. Overall, this isn’t a huge release.
* Out of the box phones with 4.02.13_G and 1.1.2 and BOOT04.06_M3S2 can not be unlocked yet, so you are also stuck. This is because new iPhone all UK iphones have a new boot loader called BOOT04.06_M3S2 and they have not tested with bootloaders other than BOOT03.09_M3S2
* If you have an out of the box iPhone with 1.1.1, then you are in good shape. Going from Firmware 1.1.1 locked to 1.1.2 jailbroken and unlocked. “”: has a good guide. Basically, what you do is to first take your 1.1.1 system and get it back to locked. You do this by first virginizing your 1.1.1 system, this gets your iPhone baseband out of unlock, that is so that the 1.1.2 upgrade doesn’t brick your phone. Then you upgrade to 1.1.2 and now you have a virgin 1.1.2 with a new 4.02.13_G baseband but with the old bootloader BOOT03.09_M3S2. You then downgrade the firmware to 1.1.1
* Going from Unlocked and jailbroken 1.1.1 baseband 4.01.xx to unlocked and jailbroken 1.1.2 according to “”: first run Oktoprep from the installer. Dock your iphone and update to 1.1.2 and don’t restore. Now run the jailbreak 1.1.2 from “Conceited Software”: Run the installer adding the source “” and download anySim 1.2.1u, reboot the phone and put it into Airplane mode and run anySIM 1.2.1u, install iWorld
* Going from 1.0.2, you need to jailbreak that phone, then virginize, then install 1.1.1 and unlock it, oktoprep it, install 1.1.2 and run jailbreak 1.1.2

64GB Solid State Drive

By the way, according to “ParisLemon”: you don’t have to wait. You can actually get a 64GB solid state drive for any computer. !>!

“Ryan Block”: cracked a PC with a solid state drive and stuffed the drive into a Macbook Pro. It is too bad that the “Samsung”: 4gb-sata-ii-ssd-drive-hands-on/ Solid State Drives aren’t available to end users yet. I’d take one and put it into every Macbook I have. They were smart and package it exactly like a 2.5″ and 1.8″ regular hard drive.

What’s more, the “128GB”: drives are coming. At that level, they really will rival hard disks for storage.

Fenix L1D-CE

Finally got this “Fenix L1D-CE”: from Amazon seller. I have to say it is amazing. It is expensive at $50, but man, is it bright. Nothing like it and it runs for hours on a single AA. Anyone who needs something for emergencies should get it. It is amazing because it uses a Cree XR-E high efficiency LED which is twice as efficient as the previous Luxeon LEDs. I’m amazed!

It will run for 25 hours at the low setting and 2 hours at maximum. If you get the two AA battery, L2D-CE, then you get 88 lumens out of it which is amazing. With L1D-CE, you get 44 lumens which is still plenty bright. I’d say get the L1D-CE for portable use and if you are throwing it in your car, get the L2D-CE

Enhanced Drivers License

When crossing from the US and Canada, you don’t need to have a passport, but you do need an “Enhanced Driver License”: which is a new identification form. Kind of nice for dummies like me who are always scared that losing a passport means that you are really stuck, so why not get both. Its a little primitive, but basically you call one of the special offices and make an appointment after January 22 and bring your proof of citizenship (like a passport), then they upgrade you.

The locatoins aren’t super convenient. There is West Seattle at (206) 764-4001 at 8830 25th Ave SW and Bothell at 425 489-1718

Email to SMS Text

Well, these addresses keep changing, but “wikipedia”: has a pretty good list of SMS gateways. The main ones connected directly so for the big US carriers they are:

| Carrier | SMS Address | MMS Address |
| AT&T | | |
| T-Mobile | | |
| Verizon | | |

There are then a bunch of a carrier independent gateways that work and are fun to try

| Site | SMS Address |
| “CardBoardFish”: |
| “Letxt”: | |
| “Quios”: | |

Finally, some folks allow you to send an SMS and turn it into email, T-mobile is the only one in the US, you text to short code 500 and the format is _emailaddress_ / _subject_ / _text_

Geometry Sketchpad

If you love spirographs when you were a kid, you’ll love this program. “Geometry Sketchpad”: is a program that let’s kids understand mathematical relationships. The site has an evaluation copy that you can try. There seem to be quite a few online resources to learn hwo to use it. You get to pay for some of it, but “”: has lots of free information. Another good site is at “”: and “”: has a bunch of discussions.
