Additional, I didn't explain the battery drain reason.
2.5G bands tend to operate on the 900MHz band width, whereas 3G tends to be
up near 1800 / 1900 / 2100MHz, thus double the power massively eating into
your battery.
This is also why when using 3G your ear get's hotter than when not, you're
effectively quite literally frying or cooking your ear.
In the UK Vodafone and O2 use the 900MHz bands for 2.5G yet Orange and
T-Mobile use 11800MHz fore their 2.5G coverage, this is why again if you use
a T-Mobile or Orange phone they get hotter when in use and personally I
found I got more head aches when using ~Orange, which I did for a brief
period.
Now I stick with O2 or Vodafone and this keeps the phone cooler and my head
aches are better.

Barbra,
For clarity, as I know it's an old conversation, but there's not quite
enough info in the responses you've received to bee clear.
Firstly, it's not 2G and 3G, it's 2.5G and 3G...
phone calls are not affected by either frequency usage, however your battery
is significantly, even if you're not using 3G for data, the battery on your
phone will be notably reduced in performance by leaving your phone on 3G
band selection by default.
2.5G ordinarily in the UK works on the 900MHz band width, although this does
change slightly depending on network, phone calls and text messaging SMS are
not affected in terms of quality or speed etc in conjunction with band width
selection. although personally, I find calls using the 3G bands seem to be a
little flatter, some what lacking in depth.
2.5G speeds range up to 86Kbps on the GPRS, general radio packet service
speed, up to 386Kbps when increased to the Edge or basic 3G.
However 3G can range from 386Kbps to 7.2Mbps, the term 3G is a little varied
and it's probably better to say edge which covers all from 86Kbps to
386Kbps, and then you get HSDPA which ranges ordinarily from 1.2Mbps to in
most cases up to 3.5Mbps and in certain areas now up to 7.2Mbps.
You can also get HSUDA which is synchronous, i.e. the same speed you get
down is that which you also get up. Ordinarily with things like ADSL
broadband and this is true for mobile broad band speeds, your download speed
is the headline figure yet your upload is much slower at more like a tenth
of that speed.
Edge in the States is also known as UTMS, so if any of you have that on your
phone that is what this is.
Importantly though here, 3G is only worth it if you're downloading large
volume content over the net like music or audio, video etc, for most of us
using say mobile sites like Amazon, G-mail or Google itself or the BBC etc,
and I repeat the mobile versions of these sites, you do not need to switch
really to 3G.

Hi
I know it is difficult to give specifics, but I just wanted some general
feedback. Using Vodafone and I know this depends on network coverage, signal
strength etc, but what is the difference between 3G and 2G speeds? If
browsing the mobile Web, would 2G be very much slower for downloading
webpages and content?
Thanks.
