Greets,

I had a question about what types of experience people have had with
data cables.

Are charging data cables certified (by UL or even produced by manuf.)?
What software if any needs to be purchased?

I have looked around and there is no available mobile office kit for
the a670, but have seen a few cables around on ebay and would like to
know the differences.

Thanks in advance,

Everything is a flip flop, Good news bad news, nothing definate.. Some
cables are made in the US, and some are made overseas, (as far as I know,
neither are UL listed).

The biggest problem with them are the rate of charge. When a phone is in
use, it usually uses more power than the charger cable puts in, in that
case, the manufacturer of the cable doesn't matter, since it is limited to
what the charger puts out. There are some cables that are powered by the USB
port, but again, it doesn't charge faster than the phone uses it when making
a call. Normally, that wouldn't matter, especially if you make shorter data
calls, but there have been an increasing number of instances lately of
people downloading files (especially XP Service Pack 2), that are huge, take
10-20 hours to download, and stop because the phone battery dies in mid
download.

There are basically 2 types of connections, Quick 2 Net (Q2N) and
NationalAccess (NA). The Q2N is circuit switched (means you dial an ISP
directly), 14.4 kb (some drivers put 19.2 on the screen and make people
think it is really that fast). The NA is packet switched and can burst up to
144K, but most people report 60-90K (faster than regular dial up, ergo you
can't call a dial-up modem), a network is usually used.

There are two main types of cables.. Serial (up to 115kb) and (USB up to
230kb).

In most instances you can use a standard windows driver, with any sort of
cable, and Quick 2 Net, to do data. The software is immaterial (Mobile
Office, Futuredial etc), you can just use a standard windows driver for low
speed, the software only makes it pretty.

When you try and use the higher speed 1X/Express/National Access/Packet
Switched, things get very complicated very quick. There are phone types,
serial or USB, cable types, use or not of compression like venturi, even if
you have a plan that allows high speed data use at the cost of minutes of
your plan. To use the high speed, while it is possible, the software (like
mobile office futurdial etc) do settings automatically to make it very
simple for the end user.

There is a lot more, and I'm sure people here will pick this to pieces, but
thats the basics as I understand it, fraid I can't be any more specific
since it depends on the actual phone itself.

I would suggest checking that wherever you buy them from will replace
your phone if it gets damaged by the charging.

I do a simple test for this. Plug the phone into the charging cable,
and take the battery out. That will show you if the phone can still
charge while idle. You can even try making a call if you want to
see if the phone will charge while calling.

I currently have 7 phones on my desk. I only charge two of them
via chargers. All the rest are only charged using charging USB
cables. I am careful however in that I only use powered USB
hubs or plug directly onto ports on the computers.
