A new bug found this week my Griffin Concepts/ Springfield iPhone repair, was when activating 'Airplane Mode'. It appears that when this is activated, or when the SIM Chip has been removed, the iPhone can not only not pick up valid signal, but even crash and reboot!
Symptoms:
iPhone 4 - activated Airplane Mode. iPhone appeared to have frozen for a few minutes, and then rebooted on it's own. After later tests I found that music that was playing while activating the switch would continue playing, until the iPhone 4 reset itself. Even after reboot, the iPhone would not seem to pick up signal. On the occasion that it would (after disabling Airplane Mode of course) no phone calls could be made, texts be sent, or received. Troubleshooting steps: Reset Network Settings (Did not work). Reset All Settings (DID WORK).
iPhone 4 - Removal of SIM Chip, and putting it back in: No service, or iPhone shows service without the ability to place or receive calls or texts. Again, the only successful method was to reset all settings (resetting network settings did not work)

How to clean your Headphone Jack
2G, 3G, 3GS and iPhone 4 headphone jacks can get dirty, grimy, corroded and/or filled with lint, which can hamper you getting the full use of your iPhone. Symptoms that may be resolved by cleaning your iPhone headphone jack is...
How can you resolved that?
Our recommendation is two-part:
DO NOT GET THE Q-TIP WET WITH WATER OR ANY CLEANER AS THIS CAN SHORT OUT DIODES NEAR THE JACK AND PERMANENTLY HAMPER OPERATION, TURN THE LIQUID INDICATOR INSIDE THE HEADPHONE JACK RED AND INVALIDATE THE WARRANTY!!!
* except for 2G iPhones that have a recessed headphone jack, you might need an adapter for non-standard iPhone headphones.
If cleaning your iPhone headphone jack did not help, check out these replacement services:
iPhone 3GS Headphone Flex
iPhone 3G Headphone Flex
- the headphone jack won't fit down all the way*
- Sound only coming out one side or speaker
- Moving the headphone jack makes audio go in/out
- Earpiece doesn't work during Phone Calls (test by hitting the volume keys while the iPhone is unlocked: if the iPhone indicates that you are changing the heaphone volume and not the ringer volume, it thinks something is plugged in when there is not! )
- You can see dust/lint inside the headphone jack.
How can you resolved that?
Our recommendation is two-part:
- Take a needle and pic out what dust, dirt and lint you can out of the headphone jack
- Take a Q-tip and pull off some of the cotton (about half from a name-brand Q-tip) and twist the remaining cotton around the stick. Make sure it's small enough that you do not have to jam it in the jack, but large enough that when you spin it, it can clean the contacts inside the headphone jack.
DO NOT GET THE Q-TIP WET WITH WATER OR ANY CLEANER AS THIS CAN SHORT OUT DIODES NEAR THE JACK AND PERMANENTLY HAMPER OPERATION, TURN THE LIQUID INDICATOR INSIDE THE HEADPHONE JACK RED AND INVALIDATE THE WARRANTY!!!

iPhone 4 signal issues after 3 days...
If your iPhone 4 begins to have signal issues and begin to act funny approximately three (3) days after you restore your data to it, you need to RESET ALL SETTINGS.
Why? It appears that the settings restored from a backup from your last iPhone, esp if it was a jailbroken iPhone, can really mess up acquisition of signal and bog down the device. Reset Network Settings doesn't necessarily work, however, you can try that first if you'd like. Rumors blame AT&T, which seems to have found a way to create reception issues for iPhones (of all kinds) that are Jailbroken.
SETTINGS > GENERAL > RESET > RESET ALL SETTINGS
Note: You will loose any of the jailbroken tricks such as a custom carrier and battery percentage, as well as any other settings such as contact sorting, email passwords (incoming and SMTP), lock settings, and more.
For those with iPhone 2G, iPhone 3G, and iPhone 3GSs, you might find the issues where every 30 seconds or so your service drops out and comes right back. To fix that, you can try this trick too to see if your service is restored.
