Frustrated with iPhone 4? Don’t jump ship too quickly.

I have noticed a high number of tweets, blog posts and news stories about people returning their iPhone’s and jumping ship to Verizon or Sprint.  People are unhappy with the AT&T cell phone network and with the new iPhone 4.

I have been on the AT&T cell phone network forever. My association with AT&T started with Pacific Bell Wireless which became Cingular which become AT&T Wireless.   AT&T uses a cellular technology called GSM.   Since I have been using GSM based cell phones for a very long time, it didn’t occur to me that non-GSM phones have limitations and was shocked to discover that the CDMA network technology (Verizon and Sprint use CDMA) can’t handle simultaneous voice and data.

The Verizon iPhone may be capable of supporting both voice and data like its AT&T cousin, a tip today says. Verizon is reportedly planning to add Voice over Revision A (VoRA) to its network that would use its EVDO Rev A 3G network to handle voice calls as well as data. Unlike usual CDMA networks, which cuts off 3G when a call comes in, VoRA would behave more like HSPA on phone networks and allow both to run at the same time.

Are you on AT&T and thinking of moving to Verizon or Sprint?  Hold on then, step back for a moment and think about how you are currently using your smart phone on AT&T.  If you currently browse the web, check email or use any apps that require the internet while you are on a voice call you might want to rethink this.  Food for thought.
