Somebody in the US has bought a c600 casing from me to do just this. You will need to change the moulded chassis as well as the aeriel cover, and I believe the power button pusher is located differently so that may require some modification.

He's promised to do a method if it all works out OK.

The t-mo SDA looks like a different animal if thats what we are talking about here and I dont see how that could be coerced into the C600 case unless under the covers the joystick and keys etc really are the same as the 2125/C600.

Anyway I agree, its not clear that we needed a hump. My Typhoons do just fine without it as does the C600 and they look a lot cleaner and fit into that otherwise useless pocket in my jeans.

I did purchase a c600 casing from Richard recently to fix a scuffed exterior on my 2125. Worked out fine (more or less). A few things to note:

(1) I replaced only the front and the perspex (in the US we call it 'Plexiglas') cover. I didn't replace the back, or the aerial cover since neither piece actually would be a stock replacement for the 2125 housing due to the hump. That was fine for me since the back of my phone was OK, it was just the front that was damaged.

(2) As Richard notes, the power button is different on a C600 than on the 2125. The mechanical switch on the circuit board is identical, however. The c600 power switch is actually an easier way to power-on the phone; after taking apart my 2125 I discovered that the reason the power-on switch on the 2125 is so wacky is because the addition of the hump prevented the switch from being activated using the c600 button. So they (presumably HTC, on Cingular's direction) bolted on the wacky power button to accomodate the hump.

You'll need to manually remove the c600 power button from the front casing, but that's quite easy (just pull it off. The plastic HTC used for the housing is about as solid as model airplane plastic - a bit disconcerting, actually).

(3) There's some contact metal that surrounds the LED housing on the top of the phone. I relocated that metal tape from the old front to the new one to ensure the LEDs would fire appropriately.

(4) It's helpful to use surgical gloves while handling the Plexiglas. Otherwise you'll run the risk of oil from your fingers getting on the wrong side of the Plexiglas, causing display difficulties.

(5) I didn't need to swap the chassis (or even disconnect any ribbon cables).

(6) I used a Torx #6 to remove the screws on the housing since I couldn't find a Torx #5. The screwdriver was helpfully labeled "for use with cellular phones." Took a bit more elbow grease than I expected, but it worked OK although I couldn't remove the additional two screws that would have enabled me to pull out the chassis and circuit board.

(7) Many have moaned the lack of a good case for their 2125s. I ended up repurposing a Nokia case (model number CTU-07); accomodates the hump just fine. I don't care for the plastic cover over the keypad so I snipped that down using a pair of nail scissors, otherwise no complaints. Had I purchased this case earlier, I wouldn't have damaged the front of the phone when I dropped it, necessitating this procedure.

Thanks to Richard and also Bret for their detailed dissasembly instructions.

Excellent info, thanks for posting it. It is encouraging to hear that the 2125 circuit board looks standard and it was the 2125 case that was hacked around to relocate the power button so things are looking good for the transplant into the C600 case.

I think it has been mentioned in here several times that the Husky HD-74502 driver set (Home Depot, around $6.00) is a great tool for phone dismantling with 4 double ended Torx bits of varying sizes. I liked it so much I also bought the HD-74501 which has the straight and phillips bits. On both units the bits store in the handle.

Thanx for the ideas!
I found out the the Cingular 2125, and the SDA (us) are exactly same hardware; I mean, shape too; the difference is the keypad-bord which seems to have the same connection, and interchangeable.

They're not the same hardware. The 2125 does not have WIFI, while the SDA (US) does.

This is just a quick update (more complete description with pictures to follow) to say that the transplant of the 2125 innards to the C600 case went well with no surprises and it is a very straightforward conversion. As far as I can tell all that the hump on the 2125 is doing is accomodating a little more metal for the antenna and my de-humped version is working fine, as I expected, just as my Typhoons work fine sans hump.

You need the complete C600 case (front, chassis and antenna cover at least) because the 2125 front does not have the power switch and IR bits and it cant be re-used for this project.

Start to finish the project took about 30 mins, most of which was fabricating an antenna using Richard Fluffcat1's patented technique and keeping the screen clean of my fingerprints and cat hair.

I now have a Cingular 2125 phone in an Orange SPV C600 case using a T-Mo SIM. It has been christened "Frankenphone".

Based on the previous post that the SDA and C600 style phones only differ because of the keyboards and that the C600 style keyboard is plug compatible with the SDA motherboard then there is a good chance that the innards from a WiFi-enabled SDA could be put into the C600 case as long as you had a spare C600 style keyboard assembly, giving you the best form factor (the C600) with the best capabilities (the SDA).

I think de-humping the Cingular 2125 may be possible because at least from the front it has the same layout as the C600. The t-mo SDA looks like a different animal if thats what we are talking about here and I dont see how that could be coerced into the C600 case unless under the covers the joystick and keys etc really are the same as the 2125/C600.

Anyway I agree, its not clear that we needed a hump. My Typhoons do just fine without it as does the C600 and they look a lot cleaner and fit into that otherwise useless pocket in my jeans.

BTW I'm the one that bought the C600 case from Richard, more news next week I hope when I attempt to turn Quasimodo into Cinderella.

Hmm, the idea of putting a Tornado inside a Faraday case definitely appeals to me...
