CacheMe needs at least symbian s60v5 and a touchscreen to work. The e72 runs s60v3 and doesn't have a touchscreen. Sorry.

Since a few weeks CacheMe supports the GcLive. CacheMe is meant to be simple, intuitive and funger friendly. It supports several map types incl Nokias terrain maps etc and supports the built-in GPS and magnetic compass if present. The switch to GcLive has allowed for several nice new features like a search function and live logging from within CacheMe. A free and unrestricted maemo5 version as well as a free but time limited symbian test version are available from the CacheMe homepage. An unlimited symbian version is available from the nokia store.

I've read this several times now and it's pretty much wrong. An electronic ompass works with 2 (or sometimes 3) magnetometers. So it can detect a magnetic field along two or three axes. See e.g. this device: The two 8 pin chips on theleft and below are two magnetometers. And one is placed 90 degrees to the other to be able to measure two axes. Now these two magnetometers output voltages in return to the magnetic field applied. Due to metal parts in the remaining device and due to limited absolute accuracy of such devices, you cannot determine the exact heading just from these two values. But once the device has been rotated and the CPU monitoring it has seen e.g. the max values returned by the magnetometers when each of them pointed exactly north/south, then the CPU is able to calculate the heading quite precise. However, if the device is switched off, it usually looses the calibration data. Also after some time the sensors behavior may change as different battery voltage levels may cause different megnetic fields to be generated by other parts in your device etc etc ... So it's not because they are supplying unregulated battery power directly to the chip.

I'd like to support the Live API with my CacheMe geocaching application. As i am supporting pretty exactly those operating systems that the official apps don't (Symbian, Maemo5, MeeGo) i think this wouldn't interfere with groundspeaks own efforts. Where can i get such documentation?

CacheMe ist vorrangig für den Online-Betrieb. Allerdings kann die eingebaute "Cloudmade"-Karte Kartendaten cachen. GPX-Dateien (Pocket-Queries) können geladen werden und einmal runtergeladene Bilder werden ebenfalls lokal gespeichert und bei Bedarf verwendet. Damit ist ein kompletter Offline-Betrieb möglich.

Ich habe gerade eine erste Test-Version von CacheMe auch für Symbian^3 online gestellt. Ich habe es bisher zwar nur auf meinem eigenen C7 testen können, aber das N8 sollte auch gehen.

You might want to give CacheMe a try.

I have just released a first Symbian test version of CacheMe. This has not yet been tested in the N8. But as it runs nicely on the C7 i expect it to work on the N8 as well.

I've just released the first test versions of CacheMe which is also available for Symbian^3 from the CacheMe homepage.
