Thanks, Raymond. It's going to take my IQ-challenged mind about an hour to make sense of your post. Might never understand it!

Raymond, I've been doing my research concerning the issue we are discussing. Bearing in mind that I'm a non-techie, can you comment on the following paragraph? Is it accurate? The GSM data evolution path will always require new network infrastructure and new phones. Every one of the future GSM data services from GPRS to EDGE to WCDMA (and High Speed Circuit Switched Data and Wireless Application Protocol) requires the purchase of a new mobile phone to take full advantage of the enhanced functionality, but all handsets will still be able to operate on the GSM network, allowing voice and CSD at 9.6Kbps. The GSM roadmap for handsets is not forward and backward compatible. This means that GPRS handsets will not work on EDGE or 3G CDMA DS base stations. A GSM carrier must make new investments in base stations for GPRS, EDGE and 3G CDMA DS, while the packet backbone may only need minor modifications after deploying GPRS. GSM also requires the implementation of IP based network elements to allow a packet overlay onto a circuit switched network. The links between the existing GSM network infrastructure entities and the IP backbone are comprised of proprietary hardware such as the Gateway GPRS Service Nodes (GGSNs) that link the Internet to the IP backbone. These are MODIFIED IP routers.
