Yes, just go in the network settings and turn off Enable 3G.
How much does an iphone 3G cost without network in the UK?
yes, but you have to have swag also.
The iPhone 3G is capable of accessing a 3G network. Some of the older iPhones and the new iPhone 4 can not access a 3G network, however. There are many droid that have the same applications as the iPhone but that will hook up to the 3G network.
If you have wifi
You can buy the iphone from apple & put it on whatever network you want to, but you cannot buy it from a phone network & change the network.
The iPhone 4 is better than the iPhone 3g. It has the capability of operating on a 4g network, which eliminates the problems you've been having with the slowness of the 3g model.
I know the the 3g 8GB iPhone is $499.00 to purchase it with out a contract
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. But i have actually just turned the wifi off because i have gotten the 3g to work so fast
There is a small chance you have no enabled 3G. To do this follow these steps. Go to Settings > General > Network and Enable 3G should be set to on. Also your area may not have 3G capabilities. In this case there is no 3G signal for 3G to work. To check 3G coverage contact your provider. Also if your iPhone is a 1st Generation and not the iPhone 3G you do not have 3G capabilities.
Either Edge (E) or 3G.
As long as you have a connection to a network(Edge, 3G, Wi-Fi) and that network is connected to the internet, yes, it is always online.
An iPhone 4g has better technology. It also includes SIRI, who answers all questions. Furthermore, the iPhone 4 has the capability to operate on the 4g network, whereas the iPhone 3g does not.
