Re: iPhone 3g Connection Problems
AT&T doesn't have good 3G service. Often you may find that you do not have 3G reception, and the phone switches to EDGE. This is not a problem with the iPhone. I live in a metropolitan area, so I do not experience problems, since 3G coverage is good. However, when i travel around, often i go to EDGE as well. Like i said this is a problem with the network and not your phone.

There are two nation-wide cell networks that allow you to browse the internet. The EDGE network (for original iPhone) and the 3G network (3G is faster, but not as widespread and can only be accessed through the iPhone 3G ). iPhone monthly plans include unlimited use of the internet, without using up your calling minutes.
If you can take advantage of a nearby wireless hub, you'll have much better speed than when you're on a cell-phone data network... but even without wireless, you can still browse, email, work and play via the EDGE or 3G cell-phone network.
i live in the UK and the reason why my iPhone 3GS does that is because some areas are not covered by a 3G network, so it uses normal internet also check in your settings that the 3G is on, as soon as i come in to a 3G area the 3G icon is back on
It sounds like you may have a poor 3G reception in your area. Even though other O2 phones are working better they may be running on the 2G masts in your area.
Try in setting/network menu turning off 3G reception, that way the device will only look for 2G masts. Your handset will give priority to 3G masts where available and sometimes will hold onto the weakest signal making poor call quality, and or dropping connection.
Advantages to using 2G only = better standby and talk time / better reception where 3G is poor.
Disadvantages = Slower web browsing / no video calls.
WEP / WPA will only apply if you are connecting using WI FI and have nothing to do with your mobile network connection.
Hope that helps?
This is normal. Most pictures you see on websites are small representations. Try going to a wallpaper or background website, click on larger pictures and zoom in then.
As for Youtube, this is normal to have ratty quality videos. this is also dependent on your bandwidth, so it may drop in quality in a low reception area, but wifi should be pretty decent, just still typical YouTube quality.
unless the dock is made for the 3g version of the phone rather than the '2g' version it may not work and even if it recognises the phone will not 'charge' the battery this is due to the pins that received the 12 volts of many docks being disconected in the new 3g phone so you have to charge via a usb which uses other pins for this purpose
The iPhone 3G has all the features of the first one, plus faster 3G data downloads, GPS, and a better battery life. Externally, the phone's casing is slightly changed, with a thinner edge and thicker middle, but a flush headphone jack and solid-colored back make up the only other major differences visually. Everything else from the screen to the number of buttons and switches on the outside are the same.
