Ok BKS,
I'll try and cover it all now, was typing on my phone before now at
home.
2G is the old GSM networks, data on these networks is at dial up speeds ie 5kb/s
3G are the current high speed networks
Next G is just Telstra's brand name for there 3G network
4 carriers run networks in Australia
3 = 2100mhz UMTS and will roam on Telstra 2g or Next G (850mhz UMTS) if your device supports it.
Optus run a dual band 3G network 900/2100 UMTS most devices support these 2 bands
Vodafone run a dual band 3G network 900/2100 UMTS network as
well
Telstra run a 850 UMTS network (branded next G) but it gets a little confusing cause they also own 50% of the 3 2100 network, so have access to that in capital cities.
There are 2 types of phones/ wireless modems..... 850/2100 or 900/2100.
You need a 850/2100 device to get the FULL speed and benifit of Telstras net work. Or a 900/2100 to get the full benifit of the other networks.
Simple as that :)
PS they all except 3 run an old GSM network but is not relevant to this subject, so have left it out.
Any device you buy from Telstra will be fully compatible with their 2 bands, others won't, Thats why your old 3G phone is not really sutible as I would guess its a old 900/2100 phone.
