Tip & How-To about Apple iPhone 3G

Tips when replacing or repairing the glass screen & digitizer on iPhone 3g & 3gs.

These tips are for those of you who have decided to take on the task of replacing your cracked screen on your iPhone 3g or 3gs.

On various videos and sites that explain how to replace the screen and digitizer (the part that recognizes touch) they tend to go a little too fast and skip a few minor details. Here are just a few that may help when taking on this task.

1) When ordering your parts make sure you order the glass screen + digitizer. Some sellers offer the glass by itself but it is just a major headache to separate the two and not worth the few bucks you save.

2) Make sure to be in well lit work space. The brighter the better (you might consider buying one of those magnifying lenses on a stand with a light on it). Get yourself one of those magnetic trays. If you lose one of those tiny screws then you are "screwed" yourself.

3) Save yourself some headache and a new bezel by using a suction cup to lift up the glass screen after removing the sim card holder (I used a paper clip for this) and the 2 screws at the bottom of the phone. Attach the suction cup right above the home button and lift carefully. There are 3 ribbon cables attached inside near the top of the phone.

4) Use some tweezers to handle some of those ribbon cables. It can get frustrating trying to use your fingers to handle those small ribbons in such a tight enclosure. Pay attention to the videos or guides you are using to find out which of ribbon cables connectors you have to flip a tiny latch up to get the cable out and which ones you can just pull out.

5) Keep all protective plastic stickies on the new parts until you are absolutely certain you are ready to install them. Any oils from your skin or dust on either the lcd or the inside of the new screen can greatly diminish the quality of your video and it will always seem like your screen is dirty.

6) I learned this the hard way. In those videos and instructions you find, they use a hair dryer to heat up the glue holding the old screen on the frame. It is much faster to use a heat gun BUT BE CAREFUL....if you heat the glass too much, the HOME button is plastic and WILL WARP. To avoid any headaches just go ahead and order the glass + digitizer assembly as well as the HOME button and ribbon cable assembly.

7) There are a number of tools that you can get much cheaper on your own and probably have laying around the house that can make the job much easier. Some may be a guitar pick, exacto knife set (the one with the various blades), some Deox-it (spell check) to clean metal contacts, some Q tips, rubbing alcohol, glass cleaner, and I also found some nice hard plastic tools, which I believe are called "spudgers" on Stanley Tools website. They basically help you hold cables back and are good for probing and wedging some of the parts open.

I hope these tips help someone that is up to doing this task. It was fun to do and also saved me some cash. Plus you have the joy in feeling that you actually fixed something! Please feel free to share this posting.

Just how can you the distinction between an iphone 3g and an iphone 3gs?

Yes there's a distinction between the iPhone 3G screen/digitizer and the iPhone 3Gs screen/digitizer. The glass is exactly the same however the cable for the digitizer relationship is not. You can inform the once the iPhone is opened by you that the link is various. The unlock iphone 3gs connection has a broader bill in the center and can not match.

What is the differeance between iphone g3 to phone gs3?

the main difference between the iphone 3g and iphone 3gs is the speed. but here are the specifications for both phones
weight: the 3gs is slightly heavier at 135g memory: iphone 3g only has two options an 8gb or a 16gb whereas for the iphone 3gs it has 8gb/16gb/32gb camera: the iphone 3g has 2mp camera that can only take pictures while the ihpne 3gs has a 3.15mp camera that can also capture videos cpu/processor: iphone 3g has ARM 11 412 MHz, PowerVR MBX-Lite graphics while the iphone 3gs has 600 MHz ARM Cortex A8 processor, PowerVR SGX535 GPU. So the 3gs is faster and it means less or no lag on apps
the 3gs has a digital compass
and the 3gs has a longer battery time than the 3g.
to summaarize, the iphone 3gs is faster, has longer battery life, and has a bigger memory (as it comes with a 32gb version).

my iphone 3g want charge..that red line is still there

Sounds like you have a dead battery. The battery in the iPhone 3G is soldered to the motherboard, making it very difficult to replace. If it is a 3GS or newer you can order a battery from iFixit.com and follow their instructional video on how to replace the battery.
