I had heard this phone would be edge capable

Is this something that can be updated by firmware?

which phone are you talking about? P900? no, it hasn't EDGE. Sure, it can be implemented in the firmware without any new hardware requirements, but I doubt will do it...

2.75 G. 3-5 times faster than GPRS, I think. Not currently supported in many countries. Hungary has it.

What is EDGE?


All present GSM networks (1991-2001) and all GSM phones are using GMSK modulation. EDGE uses 8PSK modulation.

EDGE is a modulation scheme. EDGE enhances the number of bits that can be fit into a single radio channel. GPRS provides a packet access protocol for the GSM system. So, wherever you get EDGE coverage, with an EDGE enabled phone (and you won't be able to upgrade existing ones - typically they need a new radio), you should get 2-3 times the data throughput you did before. GPRS simply gives you the 'always on' connection. Think of EDGE as the equivalent of moving from a 19.2kb/s modem to a 56kb/s modem and GPRS as the equivalent of moving from a modem connection to a network connection.

Finally, the reason you don't get 117KBit/s on existing GPRS is partly the phone capabilities (lots of DSP power required = flat battery very quickly) and partly the spectrum requirements - a 117KBit/s connection will use 8 times the capacity of a speech call for the duration of the transfer. Hence the attractiveness of EDGE as a panacea. However, just as the industry says they can get 117kb/s out of a GPRS system without EDGE but only manage 43kb/s, the 473kb/s figure is more likely to be 150kb/s or so. Of course, with 3G, the data rates will go up again and will be packet based from the start. Look for 384kb/s as the first level of service there, but only in urban environments. Phones will be dual mode and revert to GPRS outside 3G coverage areas.

Dtac and AIS here in Thailand have completed tests and are keen to roll it out

Ericsson has been selected by AIS as the sole supplier for their EDGE system in the Bangkok metropolitan area. Ericsson will also expand the present AIS GSM system for a fully integrated GSM/GPRS/EDGE solution. The contract is initially valued at USD 10 million.

I wish SE would be this proactive with their phones they always leave me spending the money and then delivering more 6months later. We already have Edge enabled Nokias. Nokia will be doing the EDGE system for DTAC the other Thailand network and are ahead of AIS and Erricsson at this stage. Good because I use DTAC but bad because I want this p900 to be my last upgrade for a while.
