How is the CDMA technology different from GSM? I am planning to buy a new phone on AT&T, which is a GSM technology phone. Should I go ahead and buy it. I have been told that the CDMA phones have better network connectivity then the GSM phones. Is it true? Some friends of mine also say that there is no difference between the two but I do not believe it. Any help anyone can provide would be greatly appreciated. Thanks in advance for your time and help.
