Nav4All goes offline in 3 days: une rumeur?

A sad news  that I learned today from  SPF forum:

Dear Customers,

It is with the deepest regret that we hereby notify you that the global navigation of Nav4All and the Tracking & Tracing will go offline in 3 days. The reason for the same is that the data licence agreement with Navteq (a 100% Nokia subsidiary) was not extended, in a totally unexpected manner. It is not possible to implement data from another supplier in our Nav4All systems within the short term. The Nav4All navigation system was developed for Navteq data. Nav4All has therefore been constrained to stop.

We greatly regret the fact that we have to suspend the operation of our service. With your help, we have developed Nav4All into a global product with 27.5 million users in 56 languages, in 5 years. This has made Nav4All the largest navigation supplier. This large number of users also has to do with the fact that Nav4All works on hundreds of different mobile telephones of many makes such as Blackberry, Sony Ericsson, Samsung, Motorola, Android, HTC, Nokia, LG, Iphone, Ipod etc.

After 5 years of testing and market development, we witnessed rapid – in fact, exponential – growth during the last two years. That growth was reported in the licence reports to Navteq. In mid-December 2009, the global coverage was extended to include the Philippines, Morocco and Kenya.

Please contact the Nav4All support desk in case you have any questions: www.nav4all.com/support. If there is any further information from Nav4All concerning the subject of this letter, the same will be published on our website: www.nav4all.com. For reasons of privacy, Nav4All does not have the email addresses of all its
customers, and we therefore request you to forward this email to the maximum extent possible, in order to ensure that everyone is informed.

Kind Regards,

Hennie J.M. Groot Koerkamp (CEO)

How to Enable Objective C++ compilation?

There are three solutions to active Objective C++ compilations

  1. By Objective C++ default file extention: .mm — This a most security way to active Objective C++ complilation. Xcode will set automatically the corresponding runtime target for the project at build time.
  2. Set Xcode project build settings(under GCC 4.2 Language) — Either add -x objectiveC++ to « Other C Flags » or set « Compile Sources As » to « ObjectiveC++ »
  3. Select the file from Xcode’s Groups & Files list, select File->Get Info and changge the file type to « Sourcecode.cpp.objcpp ».

[source: iSuppli]

With the new iPhone 3G S’s Bill of Materials (BOM) and feature set nearly the same as the previous model in the iPhone line, you might think the product’s component selection would be virtually unchanged. However, a dissection conducted by iSuppli Corp.’s Teardown Analysis team reveals some interesting changes in the parts and suppliers.
