The phone industry moves pretty quickly.   Once they're out of stock,
it's doubtful they'll return

Ebay is where you can find the older phones that you need.

I just got the Nokia 6010 go phone as part of the switch from AT&T prepaid
to Cingular. They were also offering the Motorola C139 as a free phone. You
might check on the Nokia 2600 at the Nokia site as well as Cingular site. I
use that phone with the TracFone service. In fact when it's all said and
done, I only went to Cingular since they rolled over my minutes from AT&T
prepaid plus new phone.
I had trouble on the rollover for 5 days and the solution was that a "human"
entered in the wrong rollover codes. My purchase of the Tracfone went
without a hitch even though their customer service was a little hard to
understand .
Good luck.

A quick scan of EBay shows the average price of the Nokia 6010 unlocked
new going for around $40. I've purchased phones off ebay, as long as
the seller's has a good rating it's usually the most inexpensive way to
get a specific model once that model has been phased out (often it's
the best way to get new models as well).

You're experiencing first hand somethings a real problem with the
current cell phone service structure. The cell phone service giants
(Verizon, Cingular, T-Mobile and Sprint/Nextel) completely control
which phone models are available at any given time.

They demand new models be phased in yearly from their handset vendors
(some twice a year now). You'll notice I said their handset vendors
because: Nokia, Samsung, LG, Motorola, etc... they are all traped
inside this system where the service providers are their only outlet
for distribution. Anyone who believes otherwise doesnt't realize how
embeded the situation has become.

At this point we're beyond Nokia even deciding to distribute to Target,
Bestbuy, etc.... At this point Nokia creates specific model phones with
specific features in that phone implement to the requested spec of
Cingular, Verizon, etc...

The system was put in place at a time when consumers really don't care
so much about specific models, they were more concerned with general
features. The industry has rapidly evolved to where consumers want
specific handsets and unfortunately under the current system you have
to resort to EBay to get a specific model.

I encourted this same problem about a nine months ago when I went
looking for the Audiovox SMT5600, the Audiovox had dropped in price
late 2005 and was replaced in 2006 by the Cingular 2125. At that time
the 2125 was very hard to find nad very pricey (it's sinced dropped
over $100 and with incentives can be had for a great price), it's just
an example of how the system works.

If you look at the phone offerings at any provider in the $50-$100
range... These models are being changed out all the time so the
provider can make them free phones on contract signing...... This is
the most competitive area of the market because Cingular may have a
really cool phone for free that does x,y,z and T-Mobile will want to
beat that. It's a cycle that they are all in and they could care less
about making a specific model phone available to consumers.

When you get into the PDAs and SmartPhones it's a bit different because
the business customer who these devices appeal to will often want the
same device a coworker has, but even the PDAs, SmartPhones,
Blackberries, etc.. are phased out yearly now.

Who told you that you have to use "Cingular" phones?  Why don't you sign up
for the new plan, take the free phones of whatever model seems to be the
best.  Then continue using the Nokia 6010 phones you are using now by
unlocking them.  With the new phones that you get with the contract, you can
put them away to use as emergency replacements one day, or sell them on
eBay.

To unlock the Nokia 6010, download the nokiafree program from
www.download.com, and follow the instructions for the Nokia 3595e, as it has
the same procedure as the 6010.  I have done this myself with the Nokia 6010
and know it to work.  Check out the forums on www.nokiafree.org if you don't
understand.
