1) taken apart and rebuilt cellphones and 2) dealt with hundreds of malfunctioning phones that didn't read SIM's, I'll give you some ACTUAL help.
1) remove the SIM and check for any missing pins in the slot. You can only see the first row of pins on the N1, but that's all you can see without taking the thing apart again. You should see 4 pins, but the one closest to the notched corner of the SIM doesn't really do anything.
2) If everything looks okay, reinsert the SIM, along with a couple pieces of paper. The idea is to press the SIM into the contacts in case the fit isn't as tight as before.
If you either see damaged pins in step 1 or step 2 didn't work, take it back to the repair guy. He broke it, he's obligated to fix it.
Sometimes a SIM card can come loose in the back of the phone. Take off the back of the phone and take out the battery. Locate the SIM card. It's normally white and rectangle. Pull it out and then push it back and and make sure it is tight.
Put the battery back in and let it boot up and see what happens.
If it doesn't work, it sounds like you need a new SIM card, so you will have to go to your carrier.
Turn off your iPhone 3G and make sure any cords or connector cables are removed from the device. Then, hold your iPhone 3G upright.
Locate the Sleep/Wake button and headphone jack on the very top of the iPhone. Between these two components you will see a very small hole.
Insert the tip of a paper clip into the hole to release the iPhone's SIM card tray. The small tray will pop up relatively quickly from the top of the iPhone. If there is already a SIM card in the tray, use your fingers to remove it.
Insert the SIM card you want to install into the phone facedown in the tray. Make sure the side without the reflecting panel is inserted first.
Press the SIM card tray gently back into the slot until you hear it "click" into place. Now turn your iPhone on. All of the information on the card will now be in your iPhone 3G.
not sure if this works with the 2008 but its something you can try, i put a sim card in my LX and was asking for a special code to unlock the phone, well right now tmobile isn't unlocking the sidekick, but you can trick the phone into using the sim card. First go to your settings, go to "SIM Center" and click on disable sim lock, enter in whatever your sim password is (if you dont know your sim password get your PUK (pin unblocking key) number which customer service will give you if you call 611, you can change that SIM pin by typing **05*PUKnumber*newpin*newpin#) now if you wanted to change it to "0123" if your puk was 9483992 its 7-9 digits you would type **05*9483992*0123*0123# now your sim pin is 0123. (trying not to make this super complicated) it will say sim pin not accepted click ok, now click change sim pin you can type the same sim pin 3 times if you want, 0123 0123 0123 now at the top of the screen bars will show up with a white phone beside it, go to Settings-Network Options-Scan and Select Manually, the SIM network should come up, click ok when it finds it and it will connect, now you can call and text on whatever sim you have in the phone
what phone company was the phone using before you unlocked it (sprint) ?? that slot you are looking at is probably a memory card slot not a SIM slot. everything im reading says that phone is not a GSM phone aka it doesnt take SIM cards
The carriers who use non sim phones for their network are most likely to use a CDMA 450Mhz Network. Most phones with a sim slot will work on GSM 900-1800-1900 Mhz bands, with their subdivisions (like 850-950 domain, 1800-1850). A phone with a sim card uses a RF module tuned on a specific range of frequencies. The major ones are GSM, CDMA and UMTS (HSDPA included). There are phones with support for GSM + UMTS - most 3g phones available on marked. In your case, a GSM HTC touch Dual will work on gsm networks. For verizon or other cdma networks, HTC produces a CDMA version of the Touch Dual. If you have the gsm version (the one that needs a sim) you should use it on gsm carriers.
