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.

The Samsung M5650 Lindy is GPRS, EDGE, AND 3G enabled. It should connect automatically to GPRS when it's available. (Unless you are trying to tether a PC to the internet with the phone then, it may be locked out by default.)

In the United States, Cingular Wireless is one of our cellular service providers. In order to access Cingular's 3G network, MediaNet must be used for data packet service.

On 3G phones like the new Samsung Jack the MediaNet network is not an available option when tethering a PC to the internet.

In order for Cingular's 3G phone owners to tether on the 3G network, the phone must have it's 'Internet Sharing' program unlocked. Only then can the option to use MediaNet in the Network Connections box be shown on the screen.

There is a website which explains in detail how to unlock 'Network Connections' in the 'Internet Sharing' program on the Samsung Jack 3G. You may find useful information in the site. Click here: http://tether-unlock-i637.webs.com/
