What part of the UK are you in? If you're not comfortable with a soldering iron perhaps someone who lives close to you might be able to do it for you.

london, i found a guy in wembley on ebay who helped me to find the part and says he has the skills to solder no problem who says he will do it for £15!. seems genuine as he has alot of feedback from repairing iphones on there. ive solderd a few wires in the past but i need to buy some thin tips etc to be able to do it so i might aswell pay for it to be done and i dont fancy taking an iron to my £450 phone id rather just pay £15 .

Here's how I fixed mine:

1. Remove the two screws on either side of the charging port


2. Apply a suction cup (I used my Garmin windshield mount), to the glass screen. Try to mount it right below the home button.


3. Pull the suction cup toward you and the screen should come out (bottom first)


4. You will see 3 cables running from the top right corner of the screen to the main board of the phone. 3 cables are numbered 1, 2, and 3. Remove the cables in that order. (Note: in the picture, my number 1 cable has already been detached, number 3 is underneath number 2)


5. Once the three cables are detached, the entire LCD unit is now separate from the main board. I found two youtube videos that might aid you in the process of removing the screen.

6. Look on the left side of your iPhone LCD unit; you will notice that Apple has already applied a small strip of electrical tape to the metal casing. Unfortunately, this strip is sometimes misaligned, causing light leakage. Simply add more electrical tape to anywhere you experience light leak.


Note: the tape does NOT have to cover the black rubber gasket (the part that meets the bezel when assembled). Simply apply electrical tape to anywhere on the metal frame supporting the LCD unit. Apply tape to all the places you experience light leak.

7. Reassemble the phone, reconnecting cables 1, 2, and 3, and then re-screw the two screws holding the LCD unit in place.

Your phone should now be light leak free!! Enjoy!

**All of the pictures were taken by me, except for the first, and the two youtube links.

EVERYONE PLEASE NOTE ON STEP 3: 3. Pull the suction cup toward you and the screen should come out (bottom first) PULL VERY SLOWLY! Sometimes the foam holding the connector 4 will remain attached to the screen resulting in Cable 4 being ripped or tore in two.

If this happens to you, replacement parts can be ordered on the cheap here: (Repair Parts Replacement USB/Data Port Socket for iPhone 3G) http://www.dealextreme.com/details.dx/sku.14830 Replacing this part will require some soldiering.

Anyway, reason for mentioning is that my connector and foam stayed connected to the screen upon pulling apart and the cable ripped in two. No fun, but hey that's part of hacking in the world... so right now I have a $500, iNothing! Hey, at least I have a roof over my head and food in my stomach!

lmao! exact exact same thing happened to me dude!!!! cable 4 connecter was stuck to unerside of the screen and snapped.

BTW.

Just got it fixed today
Some guy in london fixed it for me for 15 quid. Fantastic guy did all the solderin and stuff for only £15. Perfectly done too.
Id highly recomend him to anyone in the uk who has problems with there iphone out of warranty you can take your phone to him like i did or you can send it to him too. If anyone wants to know pm me and ill give you his ebay account.

Today has been a good day

Great to see your problem is solved!
Everything is fixable.. ^^d

cheers, as soon as i got my phone back i took it apart, more carefully this time when pulling it off lol, and fixed my light leak with this method worked a treat .

Think i had like the worse light leak ever worse than all the pics ive seen of it, i shuda taken a pic of mine to show everyone how bad it was.

if anyoneone snapped there cable 4 in the UK i have a spare one available.

Have just done exactly what you've described (number 4 connector got stuck to the screen!)

Bigfishman, will PM you for the guy's details from Wembley if that's OK.

Cheers
