Each mobile device is suppose to have an IMEI ( Blackberry include) i'm not
sure that without IMEI you can register on mobile network ,specialy  when
most of the mobile operators are installing EIR on their network to
blacklist stollen or non compatible device.
Yes is possible to associate IMEI to device capabilities.

This is an interesting point, which brings about two questions:


-          since you work for O2, I am assuming you know better. Honestly, I
was assuming that there is no such thing as a device without IMEI as long as
it is accepted on a carrier's Network. Don't BlackBerry's have IMEIs? I know
that operators have databases of IMEI and they are building services on top
of IMEI info. 

-          Does O2 possess a way to associate IMEI to device capabilities?
if yes, how is this achieved?

So what happens if the mobile device doesn't have an IMEI?


For example, a PDA based browser.

Yes, this is something we have discussed quite a few times in the WURFL
community. The idea is to have an extra table to match the first part of the
IMEI with a WURFL ID. This would allow an operator to easily detect device
capabilities even without an HTTP Request coming from subscriber device.

The reason why we have not embarked in such a project is that developers
typically do not have access to a device IMEI to start with.

Having said this, there is increasing interest in WURFL coming from
operators, so I would say that IMEI support in WURFL is bound to happen
sooner or later.

If you like this proposition (and you have a database of IMEI to share and
expertise in the field), please contact me offline. We could work together
on this for the developer community's benefit.

well in the way i see it most mobile development today, are least for
phones, are made towards content delivery and related things so u usuallay
need full information about phonecapabilities i mean gprs type, Egprs type,
Audio compatibility, video compatibility and so on. It will be very
difficult to fullfill the needs of several companies and developers but it
would be good to create a more standarized and extensible model to do it. It
would be also great to improve IMEI databases cause if we think uaprofs are
difficult to deal with, imei's are impossible. Its there any project to try
to merge this two identifiers. In the end both of then are usefull to
describe the same device, at least when we talk about cell phones.

Several companies create and maintain their own validated device information
repositories, which are supersets of the information available in public.
However, it takes great effort to create these repositories and they are
generally created in support of specialised products. As a consequence,
these repositories are out of reach because they are expensive. I am pleased
to report that certain key suppliers of such repositories/products are
participating in W3C MWI, with the hope that their experience may be applied
to the situation that you suggest is the case today. An extensible,
accurate, verified, trusted baseline repository of device descriptions is
one of the items on the table, which requires the participants to examine
carefully how such a repository might operate. Much of the work will be
conducted with input from the wider community, so I welcome and encourage
the feedback expressed on the public lists.

Formally, these are certainly the right standards/groups, but the track
record is disappointing in practise. In my experience, the UAProf info
actually supplied is not necessarily accurate or complete. The URLs are not
always present or correct. There is no mechanism or procedure for correcting
it - its entirely at the manufacturers' whim. Even when the data are ok,
there's a lot of useful parameters missing from the standard. There's
supposed to be a Java API, but I had to report a bug in the JSR reference
implementation months after it was approved. It's very frustrating to anyone
actually trying to cater for all the different devices right now. Standards
are one thing, but to get something working, now, WURFL is the only show in
town. I'm not an open source zealot, but WURFL has gone further faster than
the standards bodies. It works as advertised, it's responsive, it's simple
to use, it's user extensible .

The UAProf information, where provided and validated, can provide some
essential and objective information about mobile devices. It has been
recognised, however, that in many domains of content authoring and
adaptation that such information is insufficient. The DDWG will be exploring
the bigger picture, and looking at ways that a general device description
repository could be achieved, such that it can encompass UAProf and other
sources of information, avoiding replication of services, and providing the
necessary features of discovery, trust, efficiency and related information
management issues. The DDWG is specifically directed to liaise with UAProf
and other related groups to this end. Planned W3C Notes will explain in
further detail, and these shall get a public airing during this year. Input
from interested parties via the public mailing list will be encouraged. The
group will also solicit specific information from key parties where


I hope this adds some clarity.
