How to Activate GPRS in Samsung Mobile GT-M 5650 3G with idea connection. I am finding only 2 bearer types only 1) UMTS 2) WIFI GPRS is not to be seen in the list.... Is there any software to activate it...

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:

Cingular CU400 Airplane Sounds When I turn my phone on and off

This is actually really simple. I was trying to figure this out for a while. While the phone is on you simply hold down the star key (under the 7) and the phone will vibrate and say it is in vibrate mode. Then power down the phone. The next time you restart annoying jet engine sounds on startup. Viola!

What do i do if invalid smartchip appears?

Your cellphone will only work with Cingular/AT&T smartchip. What kind of smart chip are you trying to use with LG CU400. I believe no other smartchip will do.

You need to have the firmware on the phone reflash to correct this issue.
