Question about Apple iPhone 3G Black Smartphone

Phone won't ring in sleep mode

While the phone is on and the screen is on, the phone will ring for an incoming call, however if it goes to sleep, the screen turns off, the phone will not ring. When i go to use the phone it rings as if the call is coming in but the incoming call was 2 hours ago. I have exactly the same problem. As soon as i put my iphone into sleep mode (by clicking on the upper right button), i do not get any incoming calls anymore. Hours later i get the SMS telling me there was a call...
Very strange!

    Thanks a lot bdouglas :)

    I will definitely try this, but i have found out something new ... It's getting more weird.... I have disabled my 3G (in the network settings) and the phone works now perfectly... I hope your solution will work WITH 3G enabled

    I'm having the same issue & I've called Apple 3 times, done multiple restores, etc. & can't get it fixed. I've tried your solution, but I must be doing something wrong. Can you be more specific? 1. Do I just power off normally or hold down on both buttons while it powers off? 2. To power on, do I hold down on both buttons from the beginning? 3. Is the 10 & 30 seconds from the initial push of the button or 10 & 30 seconds after it completely starts up? 4. When it goes into DFU mode, will it indicate that to you? Again, I tried all these combinations & could not get it into that mode. If it didn't tell me, I plugged it in anyway & it did nothing but synch normally. Would appreciate the info. Thanks!

I had the same problem with my iPhone the only way I was able to fix it was to re-flashed the latest 2.2 firmware. Power phone off, power on by holding power and home at same time, hold power for ten seconds and then release still holding home key for another 30 seconds to put phone in DFU mode. Then plug into iTunes it will detect phone in recovery mode and allow you to re-image

LG KM900 Screen goes black when it rings and can not answer calls. No buttons wil respond and it just locks up whilst the incoming ringing happens. Answer mode is also missing from the "Common Settings".

If you have a screen protector on, the proximity sensor is covered by the screen protector. The sensor is locate on top left of the screen next to the inner camera. Cut of the piece of screen protector and it should solve the problem.

Iphone does not ring when in sleep mode

This seemed to work for me;
1.) Reset the phones network settings
2.) Reboot the phone
3.) Put the phone in airplane mode
4.) Reboot the phone
5.) Take the phone out of airplane mode
6.) reboot the phone.
I read this on another website, and it seemed to work for me.
To reboot the iphone hold down the sleep/wake button, and the home button at the same time for 6 seconds (until the apple logo appears).
Good Luck!!

"Receiving Sleep" on Brother Fax 4100

The sleep mode is only a power save mode. You may not have the machine in the correct fax receive mode. If the machine is on a line by itself it needs to be set to fax only, if line is shared with a telephone it needs to be in fax/telephone, if you share the machine with an answering machine it needs to be in TAD mode, and so forth. Each time you press the MODE key it will change the receive mode. Most people hit this key by mistake and change the MODE and the unit will not pick up calls. Press the MODE key until you are in the correct mode. To make sure the machine will print, press reports and then the 1, this will print a help list. If the help list prints you know that the machine works. Then check to make sure the machine is in the correct fax receive mode.
