In general, all Java applications are untrusted, as long as they do not contain a digital signature from a well-known and trusted source. For this purpose we have submitted the NavXS Java Mobile client to javaverified.com, which has rigorously tested it on a Nokia N95.
The application passed the test, so now we have an edition containing a digital signature that is accepted by the Nokia application installer. Nokia users can get it here: http://navxs.com/en/nokia.html.
Note that in order to dispose of the file access security prompt you will have to, after having installed NavXS, change the following settings from the Nokia main menu:
Tools > App. mgr > NavXS > Open > "Read User Data" and "Edit User Data".
These are set to "Ask every time" as default. Change to "Ask first time" or "Always allowed" and the security prompts are gone :-)

Oh, and there are new Java clients as well (v0.3.2). Get them here: http://navxs.com/en/java.html

Java Clients v0.3.0 are out.
These fixes a few more bugs, the most significant being the course and speed information that has been missing for some time due to something wrong that was not right...
Also this version has some minor design changes prompted by the Nokia N95 now being the prime test device (see previous post). Among other things, the file system access has been simplified. In the prior versions several read operations were performed per map tile while loading from the file system, to make sure the maximum disk usage limit was not exceeded. In phones who only grant one-shot file system access to untrusted MIDlets (such as most Nokias), this meant that using file system cache was almost impossible. Now, maximum disk usage is no longer monitored, and only one security prompt per tile is required when loading from cache (plus one when loading an uncached tile from the net and writing it to the file system). While it is still annoying, requiring 9 clicks to load a full map from the file system (assuming 240x320 display), it is at least almost bearable. The proper fix is to go through a verification program, obtaining a security signature, giving the NavXS MIDlet status as trusted and thus dispensing with the security prompts altogether. This is not an option for a development beta-versions such as the current, but as things are starting to come together nicely, maybe it's about time to make a final release...
Anyhoo: the new clients can be downloaded here: http://navxs.com/download/java/index.aspx
PS for Nokia N95 users: Make sure you configure the file system to cache tiles to the Micro-SD card, as untrusted MIDlets (such as the NavXS beta clients) do not have any access to the phone memory at all.
I must admit that I am a bit disappointed by the built-in GPS receiver though, which is hardly better than the one in my almost 2 years old Siemens SXG-75. To be fair, it does have slightly better accuracy and does not jump around so much as the SXG, but I expect this is more due to the Siemens guys not finding the time to add a little software filtering. The time to get a fix is just as long for the N95 as the SXG, if not longer. Hopefully future firmware updates can bring improvements (through better handling of almanac data perhaps). Another advantage of the SXG, from a developer's point of view, was that it had much more relaxed security implementations, allowing the user to grant untrusted MIDlets file system access for an entire session, rather than just one-shot access. Having to grant explicit rights to each single read or write, makes caching of map tiles to the file system in the N95 (and other Nokias) a real pain! But then again, this is a good incentive to make an “official” release of a signed, trusted NavXS MIDlet.
But all in all: The N95 is a kick-ass phone :-)

- Sending and receiving locations now works as it should.
- Some new (preliminary) help screens.
- And fixes for a bunch of non-critical but annoying bugs...
