Both.

Indoors I am most of the time with 1 o 2 bars and Outdoor depend where I am. If I lost the signal I have to swich off and on the Iphone and I get full 3g again, but after 5 min, the 3g desapear.

I always check with friends and in the places that I don´t have 3g my friends have it on there phones (Nokia and Blackberry).

Note: I bought my iphone 3 weeks ago.

Did you get the bumper case for your IPhone?

There is a problem that apple is aware of when you are holding it (IPhone 4) in your hand.
The stainless steel band is the antenna for both the cell and wifi.
When holding it, the signal strength (bars) go down to almost no bars at all. Calls drop and wifi, 3g dies.

You don't have to turn the phone completely off, you can use airplane mode and turn it off then on again after a few minutes. It's like a small reboot of the cellular part.

Is there cell phone company the same as what your IPhone is on?

What your problem sounds to me, is your cellular company is not strong(signal)in your area.

Do you have wifi hook up in your home or office?

Thanks for the reply.

I have the Bumper case but the 3g connection its the same.

Regarding the Airplane mode I already tried to switch it off and on and It´s not connecting, only can connect for 5 minutes if i switch the mobile off.

About the question of my cellular company, its the same as my Iphone is on.

Another note: At work I used to have 3g and I don´t get signal now, I check with my cellular company and they says that there is no signal problem in the area.

When I am at home I use Wifi and the connection is good, but I want to use my Iphone everywhere...

Your Welcome.

Go online and check your cell phone company (coverage map) for your area.
Double checking what they said. They r only human and we all make mistakes.

Reset network settings

To reset your network settings, tap Settings > General > Reset, then scroll down and tap Reset Network Settings.
Reset network settings

Note: This will clear your current cellular and Wi-Fi network settings, including saved networks, Wi-Fi passwords, and VPN settings.

I also enclosed a link to apple solution on call. Look it over.

Hope this works.

Hi there, I had the same exact issue. Seemed like my Iphone4 preferred the 2G although I'm in excellent 3G coverage.

I just reset the network settings now and now the 3G signal is steady. Seems that solved the problem. I'll keep monitoring and let u know.

Cheers.

The 3G signal is exactly the same with me, with 3G disabled I get 4 - 5 bars, but as soon as I enable 3G the signal drops from nill to 3 depending where I am in the house, even outside the house I get poor 3G and I am in an excellent 3G area (cell antenna is 1200ft away).

I think its a problem that apple aren't prepared to fully admit, try it out for yourself - check your 3G signal and switch it off, you will get a lot better EDGE than 3G
